Evolution du relief et paléoclimats depuis 40 000 ans sur la bordure nord du Sahara
Authors: Rognon Pierre
Published: June 2015

Résumé. - Les datations au Carbone 14 sont encore très peu nombreuses pour cette bordure du Sahara, mais leur nombre s'est accru ces dernières années. On peut donc essayer de distinguer des différences, temporelles ou régionales, à l'intérieur du Pluvial « wurmien ». Les progrès des données paléoclimatiques dans l'Atlantique oriental ou en Méditerranée permettent de proposer des explications concernant les mécanismes climatiques, encore très discutés. L'assèchement du climat au Tardiglaciaire et à l'Holocène inférieur tend à se confirmer d'après ses effets : enfoncement des oueds, forte activité éolienne, moindre alimentation des aquifères sahariens.
Prédétermination des débits de crue sur les petits bassins
Authors: Schulé Alain
Published: June 2015

Résumé. - Nombre de petits bassins des plaines océaniques françaises ne sont dotés que d'une courte chronique de mesures hydrométriques, commençant généralement en 1968. Cette chronique est constituée pour la plus grande part d'une série d'années beaucoup moins pluvieuse que la normale. - Pour améliorer la connaissance des forts débits et pour cerner « la crue de projet », on doit avoir recours à une liaison averses-crues puisque la chronique des mesures pluviométriques est, en général, nettement plus étendue. La « méthode du Gradex » convient donc. On présente des éléments méthodologiques pour une meilleure utilisation sur un petit bassin du Perche, pris en exemple : calendrier de probabilité des précipitations avec visualisation du Gradex, loi de Montane pour fournir les averses d'occurence mensuelle à n'importe quel pas de temps horaire.
La région de Kandy : chaînes et bassins dans les Highlands de Ceylan
Authors: Louchet André
Published: June 2015

Résumé. - La région de Kandy se présente sous la forme de bassins étages de forme assez régulière, aux orientations générales NW-SE, séparés par des crêtes élevées. Il convient d'y distinguer deux ensembles : les trois « K » : les vals gneissiques de Kegalle, Kadugannawa et Kandy, généralement représentatifs des structures Vijaya (env. 600 MA.) ; les alignements montagneux du Great Western, du Piduru et du Peacock, taillés dans les marbres, les métasédiments et les charnockites, représentatifs des structures des Highlands (env. 1 625 MA.). - La Mahaveli suit un tracé indifférent à la structure plissée, mais approximativement au contact des deux séries orogéniques. Il semble que l'érosion différentielle entre les deux séries ne joue qu'un rôle mineur, l'individualisation des reliefs montagneux étant essentiellement d'origine tectonique.
La formation des cirques du massif du Piton des Neiges (La Réunion) (The formation of the volcanic cirques in the Reunion island)
Authors: Kieffer Guy
Published: June 2015

Résumé. - Les cirques du Piton des Neiges résultent d'une histoire complexe. Le point de départ réside dans la formation, il y a 150 000 ans environ, d'une large caldeira sommitale. Celle-ci, créée en contexte alcalin, constitue l'originalité du Piton des Neiges qui, apparenté aux volcans hawaïens, a atteint un stade d'évolution volcanologique inconnu dans les volcans des îles Hawaii. L'érosion a ensuite accompli un travail considérable avec l'installation des exutoires de la caldeira et le recul de ses rebords. Son rôle a été facilité par l'agressivité du climat, la dénivellation et la présence de matériaux anciens très affouillables sous les empilements de coulées des phases récentes d'activité. La plus grande part du façonnement des cirques, par des processus érosifs, paraît s'être en fait effectuée après les dernières éruptions, soit en une vingtaine de milliers d'années.

Compagnies aériennes et réseaux aux Etats-Unis : évolution et typologie (Airlines and networks in the United States : evolution and typology)
Authors: Mouhot Pierre
Published: June 2015

Résumé. - Depuis la déréglementation du transport aérien régulier aux Etats- Unis, peu de compagnies nouvelles ont survécu et les grandes compagnies ont souvent résisté grâce à la multiplication de réseaux en étoile centrés sur des plaques tournantes, à des absorptions, au développement de leur flotte moyen-courrier et à l'instauration d'accords de partage de codes de vol avec des compagnies régionales exploitant des réseaux d'apport. Nous proposons une typologie des aéroports afin de comparer les réseaux des compagnies.
Le « terrain » pour les tropicalistes (Fieldwork for tropicalist geographers)
Authors: Pourtier Roland , Hugonie Gérard
Published: June 2015

Résumé. - Le terrain a toujours joué un rôle important pour les géographes effectuant des recherches dans les pays tropicaux. Cela tient d'une part aux carences des sources d'information (statistiques, cartes) qu'il faut compenser par des observations, des entretiens etc., et d'autre part à la confrontation du chercheur avec des sociétés «exotiques », porteuses d'autres valeurs. Les conditions pratiques de la recherche ont favorisé les rapprochements disciplinaires avec les anthropologues et les agronomes notamment, rapprochements facilités par l'existence d'organismes comme l'IRD ou le CIRAD. Bien des questions posées par la relation du chercheur avec son terrain ne sont cependant pas spécifiques aux « tropicalistes » mais concernent l'ensemble de la géographie. Elles dépassent en outre les problèmes purement méthodologiques car le terrain relève du vécu : il est source de plaisir et participe d'un art de vivre.

Published: June 2015

Public transportation in many countries is being used as a means of transport for travelling and accordingly people would prefer these public transportation to be scheduled properly, on time and the frequency be adequately fixed for commuters to make good use of it. It has been found that quite an amount of research work has been carried out, by way of using RFID technology in the public transportation systems towards the tracking of passengers when they board and exit buses. In addition research has also been carried out in using GPS towards the tracking of buses along with RFID technology at traffic lights, bus stops, intersections etc and also displaying expected arrival times on LCD screen at bus stops along with their current positions. Taking these aspects into consideration, an intelligent mobile bus tracking system for the Jamaican Urban Transport Corporation has been proposed and validated as a case study. The proposed system also enables commuters towards tracking the bus of their choice and also knowing their expected arrival times. So taking the above aspects into consideration, in this research the authors have proposed and validated on how control center of a bus company could track the location of a bus based on information received from RFID reader and GPS Transmitter positioned at various Bus stops and in the Bus and accordingly the expected time of arrival calculated for displaying the information on commuter's handset via Gmap. The implementation of the bus tracking scheme has been carried out using Adobe Flash player and Java.

Authors: Finco Mateus David , Reategui Eliseo , Zaro Milton Antonio , Sheehan Dwayne D. , Katz Larry
Published: June 2015

With the novelty of exergames, an alternative form of entertainment and exercise emerged especially for physical education (PE). While video games have been historically associated to problems such as obesity, social introversion and aggressive behavior, exergames brought a new perspective in which these cultural artifacts could contribute to people's education concerning the practice of physical activity. This article presents a study about the setting up of an exergame lab focusing on kids and preadolescents who usually show signs of dissatisfaction with PE. The research methodology followed a qualitative observation approach, involving twenty-four students of both genders for three months. Results demonstrated that students who were normally unmotivated to participate in PE classes showed a positive attitude regarding the exergame practices and demonstrated their willingness to collaborate with peers. The study also showed that exergaming provides situations in which students can increase the regularity of their practice of physical exercises.

Authors: Szymanski Antonia , Benus Matthew
Published: June 2015

Educators, designers and curriculum creators are interested in developing educational experiences that replicate the fun aspect of video games to increase student intrinsic motivation. This aspect, which compels players to engage with the game and persist despite failing, has the potential to increase student academic success. Researchers used mixed-methods to investigate the results of an instructional design that attempted to replicate the fun aspect of video games in a remedial algebra class. The study offered insight on the ways in which student motivation might be better developed and refined in educational settings using game-based approaches. Results indicated that some students enjoyed the freedom of choosing their own quests to complete while others felt lost in the new environment. It is important to game and instructional designers to scaffold the transition from traditional classroom to a game-based classroom.
The Influence of Individual Characteristics on Knowledge Sharing Practices, Enablers, and Barriers in a Project Management Context
Authors: Marouf Laila N. , Khalil Omar E. M.
Published: June 2015

The knowledge management (KM) literature in general is short on field evidence concerning knowledge sharing (KS) practices in project management settings, where knowledge occupies a central place. In addition, research on KS enablers and barriers has largely overlooked the fact that individual characteristics may influence the choice to share knowledge. This research explored departmental KS practices, enablers and barriers at a Middle-Eastern project management company. It also investigated the influence of a number of individual characteristics on KS, enablers and barriers. The findings confirm that Knowledge is partially shared within departments, and the employees have varying views on KS enablers and barriers. Although many do not perceive organizational enablers as catalysts for KS, they somewhat believe that the information technology (IT) enablers do facilitate KS. The employees, however, do not believe that the identified individual, organizational and IT barriers hinder KS. In addition, gender, age, department type and job type have varying effects on the perceived KS practices, organizational enablers, and IT enablers and barriers. These findings and their implications are further discussed in the paper.

Authors: Pathak Hrishikesh , Das Sanghamitra , Doley Rakesh , Kashyap Satadru
Published: June 2015

In the present study an attempt has been made to investigate the effect of cutting parameters (cutting speed, feed rate, and depth of cut) on surface roughness and material removal rate (MRR) during dry turning operation of AISI H13 tool steel as per Taguchi's experimental design technique using an L9 orthogonal array. Signal to noise ratio (S/N) results and Analysis of Variance (ANOVA) were employed in order to investigate the optimal and significant cutting characteristics of H13 tool steel respectively. This paper focuses on optimizing the cutting parameters for minimum surface roughness and maximum MRR of H13 tool steel using high speed steel (HSS) as the cutting tool during turning. The results indicated that feed has a significant influence on surface finish and depth of cut on MRR when turning operation was carried out with HSS cutting tool. An artificial neural network model and regression equations were also developed to obtain minimum surface roughness and maximum MRR at different cutting conditions.
Skin Detection with Small Unmanned Aerial Systems by Integration of Area Scan Multispectral Imagers and Factors Affecting their Design and Operation
Authors: Sweetnich Stephen R. , Jacques David R.
Published: June 2015

Dismount skin detection from an aerial platform has posed challenges compared to ground-based platforms. A small, area scanning multispectral imager was constructed and tested on a Small Unmanned Aerial System (SUAS). Computer vision registration, stereo camera calibration, and geolocation from autopilot telemetry were utilized to design a dismount detection platform. The test expedient prototype was 2kg and exhibited skin detection performance similar to a larger line scan hyperspectral imager (HSI). Outdoor tests with a line scan HSI and the prototype resulted in an average 5.112% difference in Receiver Operating Characteristic (ROC) Area Under Curve (AUC). This research indicated that SUAS-based Spectral Imagers are capable tools in dismount detection protocols.

The process of tourism development has come to include, step by step, the expansion potential of areas where it could be practiced in less accessible natural spaces, which are more problematic from the point of view of tourist penetration and the organization of tourism activities. In this context, making tourism under the umbrella of this concept of expansion, has led, on the one hand, to the expansion of protected natural areas, to their advertising and implicitly to the increase of demand for this type of tourism, and, on the other hand, to the amplification of danger posed to the integrity of the ecosystems included in the tourism circuit. The paper, starting from the actual context of sustainable development, highlights the fact that the tourism potential of protected natural areas constitute an important factor for sustainable development only, if is doing in condition of responsibility and respect for environmental conservation and regeneration of environmental resources

Numerical Analysis of the Influence of the Parameter of Ductility of Reinforcing Steel on the Behaviour of Single-Span Reinforced Concrete Beams from the Viewpoint of Experimental Investigations
Authors: Wieczorek Mirosław
Published: June 2015

One of the fundamental elements applied in reinforced concrete structures are beams. Depending on the proportion of the dimensions and the way of imposing the load, two fundamental mechanisms of destruction are to be distinguished (brittle destruction caused by shearing the supporting zones or flexural destruction in the zone of the span). The present paper provides the results of the analysis of four reinforced concrete beams with the dimensions 4000×400×200 mm, reinforced with steel of varying ductility. The aim of this analysis was to reflect and to provide more detailed information about the phenomena observed in the course of laboratory investigations. The numerical models were constructed in compliance with the system ANSYS, applying volumetric elements Solid 65 and bars Link 8. In order to determine the relation σ-ε of the steel an isotropic model of strengthening according to Misses was implemented in the system ANSYS. The behaviour of concrete was represented making use of the material model Concrete. The parameters applied in the material models were obtained basing on laboratory tests of materials. The results of calculations have been quoted in the paper, as well as their comparison with the results of investigations carried out in the laboratory.
Different Approaches to Modeling of Proportional Damping
Authors: Šána Vladimir
Published: June 2015

This article is focused on the comparison of mathematical models, which are usable for description of damping in the linear proportional systems with single and multi degrees of freedom (SDOF and MDOF). The viscous and hysteretic models have been applied on the SDOF system. The hysteretic damping, Rayleigh's and Caughey's damping matrices have been mentioned and considered for modeling of damping in systems with more than one degree of freedom. The wellknown Rayleigh's model is proportional to the mass and stiffness matrices. Caughey's model is more general than Rayleigh's. This model is able to prescribe an arbitrary number of damping ratios, but on the other hand using odd number of members in Caughey's series should not be allowed due to the negative values of damping ratios in higher modes, which brings self exciting effect. The hysteretic model is defined only in the frequency domain therefore the frequency response functions of each model have been compared.

Authors: Wieczorek Barbara
Published: June 2015

The paper presents the results of calculations, taking into account a material model (isotropic reinforcement according to Misses), representing laboratory tests of additional reinforcement. Complying with PN-EN 1991-1-7:2008 (EC1) and PN-EN 1992-1:2004 (EC2) this reinforcement is applied in reinforced concrete slab-column structures in order to protect them against progressive collapses. Additionally, an analysis was carried out, considering, the effect of applying in the material model the true stress-strain curve. In the course of these experimental investigations the values of displacements caused by the exerted load were compared with the values of numerical calculations.

Authors: Bencat Jan , Stehlikova Maria , Skarupa Milan
Published: June 2015

Full–scale dynamic testing of bridge structures can provide valuable information on the service behavior and performance of structures. With the growing interest in the structural condition of highway bridges, dynamic testing can be used as a tool for assessing the integrity of bridges. From the measured dynamic response, induced by instructed passing trucks, modal parameters (natural frequencies, mode shapes and modal damping values) and system parameters (stiffness, mass and damping matrices) are obtained. These identified parameters can then be used to characterize and monitor the service of the bridge structure in the future. Analytical models of the structure can also be validated using these parameters [1,2]. The paper presents a procedure for estimating the traffic load bearing capacity of the steel arch highway viaduct Bridge Structure 205 (DC1–9, 755 m) constructed on Highway D1 in Nord Slovakia (Fig. 1) over the natural hollow basin via dynamic tests of the viaduct structures.

Composite Slabs with Prepressed Embossments – Longitudinal Shear Resistance
Authors: Holomek Josef , Bajer Miroslav , Barnat Jan , Vild Martin
Published: June 2015

Composite slabs with prepressed embossments present an effective solution for horizontal structures. Prepressed embossments ensure composite action after hardening of concrete. Longitudinal shear failure mode typically governs if the shear resistance of embossments is not sufficient for full composite action. Mutual separation of thin-walled sheeting from concrete and its deformation inside the rib is characteristic for this failure mode. Design methods for composite slabs use full scale bending tests in several series to determine their bearing capacity. A less expensive alternative is to use small-scale shear tests to determine shear characteristics of the sheeting. This paper presents detailed numerical models of slab in shear and models of slab in bending with and without embossments. These models are compared with previously performed experiments. Key WordsComposite slab; steel sheeting; concrete; prepressed embossment; longitudinal shear; experiment; numerical model

Authors: Ravinger Jan , Snirc Lubos
Published: June 2015

Thermo-steel panels compose from steel thin-walled profiles and polystyrene. They are used as wall construction elements. We must follow stability problems. Finite strip method (FSM) has been used. Special arrangement had to be done for investigation of stability of thermo-steel panels. In thermo-steel panels compression stresses are carried in thin-walled steel profiles only. It means that polystyrene enter into stiffness matrix but it does not have increment in geometric matrix. Numerical examples were oriented for investigation of thermo-steel panels with 145 and 250 mm thickness. Obtained results proved ability of thermo-steel panel to be used as wall panel for two storey building.

Authors: Psotny Martin , Havran Jozef
Published: June 2015

Von Misses truss is one of the best examples to explain nature of non-linear solution and define the snap-through. Linear buckling analysis and nonlinear finite element approaches are compared in presented paper. At the present time theoretical models for the evaluation of the ultimate load assume a structure with imperfections. The peculiarities of the effect of the magnitude and mode of initial imperfections are investigated. Effect of member stiffness on the load level in critical point of nonlinear solution, as well as the relative position with respect to the critical load from buckling analysis are analyzed. To obtain the nonlinear equilibrium paths, Newton-Raphson iteration algorithm has been used. Obtained results are compared with those gained using ANSYS system.

Published: June 2015

This paper deals with static analysis of load-bearing steel grid of a transparent roof. Ten structures with various spans (from 12.58 m to 30.08 m) and different heights (from 2.494 m to 7.471 m) have been modelled and analysed. The calculations were repeated for two common used types of the cross-sections - (60 x 40) mm and (60 x 60) mm. Permanent loads (the self-weight, the weight of glass panels) and variable loads (snow, wind) were taken into account. Obtained results were verified by four additional structures. The architects can use resultant graphs (the dimensions, maximum axial forces and maximum vertical displacements) in first stage of the design.

Application of Fuzzy Set Theory to the Serviceability Limit State of a Steel Beam under Bending
Authors: Vales Jan , Kala Zdenek , Melcher Jindrich
Published: June 2015

Deformations of an I-section steel beam under equal end moments are studied in this article. Initial geometric imperfection of the beam axis was introduced according to the Eurocode standard. Numerical studies have shown that the lateral deflection of slender beams under major axis bending can be relatively high. The acceptability of high values of lateral deflections within the framework of the serviceability limit state is discussed. In the next part of the paper, the limit value of maximum deflection was introduced as a fuzzy number. Fuzzy analysis of the maximum moment, which causes maximum deflection, was performed. The slenderness values of beams for which the serviceability limit state is the limiting condition for design were identified.

Published: June 2015

Hypokalemia is a common electrolyte abnormality and if neglected, it may be fatal. This type of electrolyte abnormality is seen in distal renal tubular acidosis (RTA). Respiratory paralysis in distal RTA due to hyokalemia is a rare clinical entity described in the literature. Here we discuss one such case: a 25-year-old female presented with complaints of acute onset symmetrical weakness of bilateral lower limbs that rapidly progressed to involve trunk, upper limb and neck. Later on, she developed respiratory paralysis and was put on mechanical ventilation. Diagnosis of distal RTA with hypokalemia was made and managed successfully.
Obstetric fistula in Assam, India: a neglected cause of maternal morbidities and mortality
Authors: Jungari Suresh , Govind Chauhan Bal
Published: June 2015

Each year between 50,000 to 100,000 women worldwide are affected by obstetric fistula, a hole in the birth canal. Obstetric fistula is one of the major cause for maternal morbidities and mortality and it has been successfully eradicated in developed nations. Women who experience obstetric fistula suffer constant incontinence, shame, and social segregation. Obstetric fistula is prevalent in African and Asian countries, including India. In India, data has been collected in a large scale survey of district level household survey regarding obstetric fistula and its causes. In this study, efforts are endeavoured to understand the prevalence and causes of obstetric fistula in Assam state, India, where prevalence of obstetric fistula is very high (4.5%). Chi-square test was applied to determine the affecting factors of obstetric fistula. Results showing the socioeconomic status, education, place of residence and age group are important determinants in variation of fistula prevalence among women.
A minimalist technique for insertion of intrauterine devices
Authors: Goldstuck Norman David
Published: June 2015

The world’s population is approaching 7 billion. As a general rule, the countries with the highest population have the least available healthcare resources, the most notable exception being the United States of America (USA). Most of these countries have an urgent need to reduce their populations. The intrauterine device (IUD) is used by the largest number of contraceptives world-wide and it has a proven record in reducing unwanted pregnancies. Its efficacy rate as a long-acting reversible contraceptive is matched only by subdermal implants which are not as cost effective. Although the rates of pelvic infection are elevated in many countries with low-resource health care systems, we now know that pelvic infection rates are independent of IUD usage. This is therefore no longer a contraindication for using IUDs on a large scale in family planning programs. The technique of IUD insertion as described in most textbooks and journals is unnecessarily complex and based on ritual rather than good clinical evidence. This is particularly interesting in that at a time where we prefer evidence based medicine there are still so many clinical practice sacred cows. This article advocates a simplification of the technique for inserting IUDs. The scientific rationale for simplifying the technique is presented, as well as evidence that it is as safe if not safer than the currently suggested methods, if used for the correct type of IUD acceptors.

Authors: Gurland Barry J. , Page William , Small Brent , McArdle John J. , Plassman Brenda L.
Published: June 2015

The aim of this study is to estimate heritability of incident limitations on personally desired activities within the eighth decade of life. We measured self-rated ability to perform ten personally desired activities in 1606 male veteran twin pairs at baseline and four years later. At follow-up, 33% of the cohort reported more limitations in desired activities. Among twins who completed both assessments, there were no statistically significant differences in incidence rates of limitations as a function of zygosity. Sensitivity tests showed the same for change scores; and that, if cognitive impairment or death are deemed to belong among limitations of desired activities, zygosity contributed 10% to new limitations at follow-up. Maintaining personally desired activities over four years in the eighth decade is not subject to substantial genetic influence. However, if death and cognitive impairment are added to incident limitations, then genetics plays a modest role. In all cases, unique environment is the predominant influence.

The health of an individual depends on both his/her physical and psychological condition. In recent years it has been observed that chronic patients have frequently an affected psycho-emotional state. The purpose of this study is to investigate anxiety and depression in patients with chronic diseases and the correlation of the results with daily physical activity levels and individual health levels, as well comorbidity. This study included patients with chronic diseases that were treated in a local general hospital or were visiting often outpatient clinics of the same hospital due to their condition. The sample in this particular study included 204 patients; 118 of them were women and 86 men. From the total sample that participated in our research, 118 (57.8%) were females and the majority of the participants were secondary/basic education graduates (67%), married (71%), living in urban areas (53%). Hypertension was the most frequent chronic disease in our sample, followed by hypercholesterolemia and diabetes mellitus. Comparing the occurrence of depression and anxiety symptoms in both questionnaires in relation to the expected frequency in the general population, significant levels of depression and anxiety symptoms were recorded. Taking into consideration the findings of this research, anxiety and depression symptoms can have profound effects regarding the control of chronic diseases, the patients’ quality of life and their general health.

Goldberg’s International Personality Item Pool (IPIP) big-five personality factor markers currently lack validating evidence. The structure of the 50-item IPIP was examined in two different adult samples (total N=811), in each case justifying a 5-factor solution, with only minor discrepancies. Age differences were comparable to previous findings using other inventories. One sample (N=193) also completed additionally another personality measure (the TIPI Short Form). Conscientiousness, extraversion and emotional stability/ neuroticism scales of the IPIP were highly correlated with those of the TIPI (r=0.62 to 0.65, P=0.01). Agreeableness and Intellect/Openness scales correlated less strongly (r=0.54 and 0.58 respectively, P=0.01). The IPIP scales have good internal consistency (a=0.88) and relate strongly to major dimensions of personality assessed by the two questionnaires.

This study will explore the relationships among strengths self-efficacy, resourcefulness, stigma experience and mental health recovery in community-dwelling adults with serious mental illnesses. Mental health practices have focued on psychopathphysiology. Stigma heavily plagued clients with mental illnesses and is one of the greatest barriers to mental health recovery. Personal strengths like strengths self-efficacy, people’s confidence in using their personal strengths, and resourcefulness, the ability to carry out daily activities, have been linked to positive mental health. However, the linkage between strengths self-efficacy, resourcefulness and mental health recovery remains uncharted. A cross-sectional, descriptive, mixed methods study will be conducted. A funded study by the Sigma Theta Tau, Upsilon Eta Chapter, August 2013, involving a convenience sample of 100 participants is planned. Included are community dwelling adults between 21 to 65 years old having been diagnosed with serious mental illnesses. Clients with current co-occurring substance abuse will be excluded. Participants complete questionnaires and undergo an interview. Correlations among the study variables will be examined. Regression analysis will determine if recovery can be predicted by strengths self-efficacy, resourcefulness and stigma experience. Interview data will be transcribed and analyzed by thematic analysis. This study will look beyond clients’ disability to focus on their recovery and healing capacities such as strengths self-efficacy and resourcefulness. Findings will expand our knowledge about mental health recovery. Knowledge gained from this study may pave the way for future nursing strategies to aid recovery and inform the development of positive, strengths-based interventions.
Parental perceptions of health-related quality of life of Albanian children with epilepsy

Published: June 2015

Epilepsy adversely affects the health-related quality of life (HRQoL) of children living with it. Even though almost 80% of children with epilepsy live in developing countries very little research has been conducted with the specific population. The present study took place in Albania and aimed to investigate parental perceptions of the HRQoL of their children with epilepsy. Considering the well-defined gender roles in the Albanian traditional family it was expected that mothers and fathers reports of their children’s HRQoL would differ. Results showed no differences in maternal and paternal reports; instead there was a moderate correspondence between the reports across all dimensions. Parents also reported the highest scores of HRQoL in the interpersonal dimension and the lowest scores in the intrapersonal dimension. The findings have implications in the context of future research and also medical care for children with epilepsy in Albania.

High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) has been applied to patients with diffuse large B-cell lymphoma (DLBCL); it is well established that ASCT shows significant survival benefits for chemosensitive relapse. However, half of relapsed patients are resistant to salvage chemotherapy, indicating that they are not suitable for ASCT. We retrospectively analyzed the clinical records of 47 patients with DLBCL classified as high or high-intermediate (higher) risk, according to the International Prognostic Index, who underwent upfront ASCT in first complete remission (CR1). Compared with 10 patients with similar characteristics who did not receive ASCT, event free survival at 5-year was significantly superior in ASCT group. Toxicity of ASCT was acceptable and therapy-related death was not observed. We therefore propose that upfront ASCT for higher risk DLBCL in CR1 might provide survival benefit, probably because the high-dose therapy removes minimally resided tumor.
Angioimmunoblastic T-Cell Lymphoma Presenting with an Acute Serologic Epstein-Barr Virus Profile
Authors: Beer Timothy , Dorion Patrick
Published: June 2015

Angioimmunoblastic T-cell lymphoma (AITL) is an aggressive peripheral T-cell lymphoma typically characterized by prominent lymphadenopathy and B-symptoms at the time of presentation, polyclonal hypergammaglobulinemia, autoimmune hemolysis and frequent but highly variable involvement of Epstein- Barr virus (EBV). Lymph node biopsy findings typically include effacement of nodal architecture, polymorphic infiltrate, atypical T-cells (usually CD4+/CD10+/PD1+) and prominent proliferations of high endothelial venules and follicular dendritic cells. However, this classic constellation of pathologic findings is often initially obscured by a prominence of EBV+ B-immunoblasts with or without associated peripherally circulating EBV DNA. Here we document the first reported case of an acute serologic EBV profile (VCA-IgM) in a patient with AITL, and we recommend that clinicians maintain a high index of suspicion for AITL in the appropriate clinical scenario, irrespective of Epstein-Barr related findings.

Published: June 2015

Isolated splenic inflammatory pseudotumors (IPT) are extremely rare, typically benign, inflammatory lesions with varied clinical presentations that pose a diagnostic challenge to clinicians due to their similarity in appearance to neoplasms. We present the case of a young woman diagnosed with a splenic IPT following investigation for persistent anemia, raised inflammatory markers, and polyclonal hyper-gammaglobulinemia, whose symptoms resolved completely following splenectomy. This case highlights the need to consider this diagnosis when evaluating patients with a splenic mass of unknown etiology.
