Authors: Mincă D.G. , Cîrstoiu C. , Furtunescu F.L. , Costea R.V.
Published: May 2018

Introduction. Cancers of bone and articular cartilage are relatively rare, and a global analysis was not performed up to present in Romania due to the lack of a national registry for these diseases. This study aimed to explore the hospital burden due to malignant neoplasm of bone and articular cartilage in Romania and the general characteristics of the hospitalized cases. Materials and methods. We used the data reported in the routine statistic system during 2012 and 2016 and we analyzed the number of cases discharged from hospitals by age group, gender, and duration of hospitalization. Results. The number of hospitalized cancers of bone and articular cartilages decreased by 17% in the last five years (2012-2016) but this decrease was higher in other/ unspecified cancers (22%) and lower in limb cancers (10%). Among the 1872 cases reported in 2016, 47% were limbs’ cancers and the rest, cancers of others/ unspecified sites. Males accounted for 62% of all cancers (58% of limbs cancers and 65% of other cancers, p=0.001, Chi2 test). Distribution by age showed that 17%, 62% and 21% of the cancers occurred in age-groups 0-14, 15-64 and 65+ respectively, but limbs cancers occurred in a significantly higher proportion in children (29% vs. 7% of other cancers, p<0.001). 16983 days of hospitalization were reported in 2016 for this pathology, with an average length of stay of 9.07 days (9.37 and 8.81 days in limbs and other cancers respectively). Conclusions. More detailed analysis of routine reported data is required for understanding the characteristics and trends of bone cancers in Romania.

Published: May 2018

Introduction. Soft tissue sarcomas (STS) are rare entities of soft tissue cancers. Their incidence is low, of only 1% of the malignant tumors. In terms of localization, most of the STS affect the extremities, and their incidence is much higher in children than in adults. Material and method. The present paper is a retrospective study that includes tumors with lower limb localizations, including the bony pelvis, over a 3-year period (2013-2016). The study group consisted of 29 patients who, following the MRI examination, were diagnosed with softtissue tumors. Of the 29 patients, 17 patients had a MRI (magnetic resonance imaging) and an anatomopathological diagnosis of leiomyosarcoma. The location of the tumor, its characteristics, and the relationship with the adjacent anatomical structures were analyzed in all cases. Results. The ages of the final group of 17 patients ranged between 28 and 84 years, with female predominance. In terms of localization, one showed a muscle tumor in the pelvis, namely left oblique muscle, other cases being located in the thigh and knee. A special importance was given to the superficial and profound location. In 5 cases, the tumor was localized in subcutaneous fatty tissue, thus superficial. In terms of the contours of the tumor, well-defined margins were present in 11 cases, and poorly defined contour in 6 cases. Regarding the size, the leiomyosarcomas in our study had dimensions between 5.2 cm and 18 cm, and their structure was inhomogeneous, with the presence of necrosis and calcifications. Necrosis was found in 14 cases, and calcifications were present in 68%, being more frequent than necrosis. Except for the necrotic areas, the contrast enhancement was intense. Conclusions. Although the diagnosis is always histopathological, the MRI plays an important role in defining a precise localization and tumor characteristics.

Published: May 2018

Introduction. Cutaneous malignancies localized on the nasal pyramid are one of the most frequent non-melanocytic skin cancers with a great psychosocial impact. A predominant pathology of the elderly is distinguished by slow development, with a tendency to ulceration and addressability to medical services in advanced local stages. Reconstruction after oncologic intervention is diverse, locoregional flaps, grafting, and simple direct sutures can be made, the case per se dictating the appropriate attitude. The variables to be considered are location, size of the remaining defect and quality of potential donor areas. The following are also taken into account: reduction of morbidity, increasing quality of life, patient’s psychological impact. Materials and methods. 7 cases of basocellular carcinoma of the nose addressed between 2017- 2018 are described throughout an observational analysis based in the Emergency Hospital for Plastic Reconstructive Surgery and Burncare in Bucharest, referred to by various reconstructive methods, depending on the particularities encountered. Locoregional flaps-bilobed, nasogenian, frontal, dorsal nasal - as well as full-thickness skin grafts and simple direct sutures were performed. Results. Carcinoma excision was complete and safety margins were confirmed histopathologically. Evolution of postoperative patients was favorable without complications. Conclusion. There are numerous surgical options for repairing nose defects. Oncological radicality and satisfactory aesthetic and functional outcome are the main objectives in choosing the method. The aims of reconstructive surgery are functionality of the nose, aesthetic appearance with finer scars, preserving the aesthetic subunits of the nose, but also the relationship with the neighboring structures.
Multidisciplinary Approach in the Treatment of Malignant Bone Tumors
Authors: Marinca L. , Pop D. , Moraru O. , Stoica I.C.
Published: May 2018

Introduction. There are two types of tumor lesions at bone level: primary tumors and bone metastasis. These lesions cause a decrease in the structural strength of the bone that may lead to fracture. The goal of the orthopedic treatment is to resect the tumor, alleviate symptomatology, and restore the function of the limb. The orthopedic treatment consists of two phases: tumor resection and limb reconstruction. Treatment of such lesions implies extensive preoperative investigations to determine the local and general extent of the tumor and procedures aimed to facilitate resection. Case presentation. We present the case of a 58-year-old male, diagnosed with clear cell renal carcinoma three years before and treated by nephrectomy. Two months after surgery, the patient started reporting moderate pain in the hip, which gradually intensified. He was first seen in Foişor Hospital in December 2018 when a pathologic bone fracture in the trochanteric region of the right femur was discovered at the radiologic exam. This was supposed to be a bone metastasis from the previously operated renal cell carcinoma. The MRI investigation showed the presence of a large, polylobed bone tumor with an inhomogeneous structure, sized 80/ 72/ 82 mm extending in the adjacent soft tissue. Bone scintigraphy of entire skeleton revealed no other lesions and abdominal MRI exam revealed neither the recurrence of the tumor or the presence of abdominal metastasis. Significant vascularization of the tumor, from branches of the deep femoral artery, was evidenced on the Angio Computer Tomography. Due to the known profuse bleeding of such lesions, an angiography with embolization was also performed. Embolization was done with PVA particles, with a lack of post-embolization load. The Angio Computer Tomography scan performed at three weeks after embolization showed a reduction in size of the tumor. In March 2018 patient underwent bone resection and reconstruction with a G.M.R.S. tumor prosthesis. Resection was performed in a complex team involving also two vascular surgeons. The pathology exam confirmed it was a renal cell carcinoma bone metastasis. Results. At one week after the surgical procedure, the operative wound was healing, the patient had no pain, and he was gradually regaining ambulation. Conclusion. Surgical treatment of such neoplastic pathology is difficult and involves a multidisciplinary approach consisting of disciplines such as oncology, orthopedics, vascular surgery, and pathology. It also implies a significant contribution from radiology and interventional radiology.

Published: May 2018

Introduction. Efficient management of a segmental resection or major osteolysis in the distal femur secondary to a tumor formation remains a controversial problem. Available options include the use of a modular or customized megaprosthetic implant. Modularity allows versatility for reconstruction and avoids the delay required to make a customized implant. Hypothesis and type of study. Performing a clinical and radiological retrospective study that aims to evaluate long-term efficiency in the use of megaprostheses in segmental distal femur resections. Elaboration of patient selection criteria for modular prosthesis. Materials and methods. We followed retrospectively 33 patients for 5 years from the time of the first surgery. We evaluated the implant stability, the late complications rate, and the long-term functional recovery of patients with distal femoral tumors who underwent segmental resections and subsequently reconstructive arthroplasty. Results. Thirty of the 33 patients maintained a mobile knee joint. An intermediate staging was performed at 30 months, which determined tumor recurrence in 2 patients, aseptic degradation of the components in 3 of them, and septic degradation in two of the evaluated cases. Because a tumoral recurrence occurred on the 45th month, the need for amputation of the prosthetic limb was imposed. The degradation of the polyethylene component (in 5 cases) was observed in the 5-year assessment. The functional results were excellent with the Musculoskeletal Tumor Society Score of 88% and a Toronto Extremity Severity Scale Score of 94%. Conclusions. Patients with distal femoral bone tumors undergoing modular reconstruction prosthetic arthroplasty have excellent functional results with retaining the affected limb and knee mobility. There was a close correlation between correctly applying the selection criteria for patients undergoing prosthesis intervention and functional recovery results.

A 20-year-old patient presented to the emergency service with radial distal epiphysis after a minor trauma. The radiological examination indicated a fracture at the radial distal epiphysis on the background of a tumor that occupied the radial epiphysis in its entirety, with cortical burglary in some places. When consulting the oncologist, a surgical intervention for biopsy material harvesting was performed. The anatomopathological exam showed: multiple fragments microscopically representing a tumor proliferation consisting of two cell populations, mononuclear cells, densely cellular and strobe pattern; areas of infarction, haemorrhage areas, rare intratumoral osteoid formation zones; appearance of giant cell tumor. The immunohistochemical examination confirmed the anatomopathological diagnosis adding, therefore, the aggressive character and the local relapse. The oncologist decided that it did not require oncology treatment but only orthopedic treatment. Orthopedic treatment required repeated surgery at intervals of about 5 months apart, caused by tumor recurrence. The first intervention consisted of 1/ 3 distal radius resection and replacement with a graft harvested from the peroneum. Tumor recurrence after 5 months required extirpation of tumor tissue and filling of caries caused in the graft with a fluid bone substitute. Recurrence after another 5 months required removal of the graft that was invaded by the tumor and cubitusmetacarpal arthrodesis fixed with a screw plate. Currently, the patient is undergoing complementary oncology treatment finally initiated by a medical oncologist.
Pelvic Chondrosarcoma - Therapeutic Options (Literature Review)
Authors: Popescu R. , Cuculici Șt. , Cristea Șt.
Published: May 2018

Chondrosarcoma is a mesenchymal malignant tumor (primary or secondary) which is characterized by a cartilaginous mass formed out of neoplastic cells. It is one of the most frequent malignant bone tumors (after multiple myeloma and osteosarcoma), affecting more males than females (Ratio M:F=2:1). It appears with predilection in the pelvis and long bones - mainly the proximal portion of the humerus and femur. It is a unique primary bone tumor through its chemotherapy and radiotherapy resistance, the only effective treatment being the surgical one. As far as the pelvis is concerned, it is important to determine the location, the dimension, and the relation with the nearby structures of the tumor, in order to establish if it is possible to do a complete excision of the tumor and adapt the subsequent reconstruction of the pelvis. In the excisions of the pelvic chondrosarcoma, the choices are conservatory surgery (limb saving) and the radical surgery (conventional pelvic resection). The oncological resection is the primary goal, but the functional result and the patient’s quality of life are also very important.

Published: May 2018

The buckling analysis of carbon nanotubes without and with hetero-junctions is described in this paper. The buckling behaviour was investigated by the finite element method and the carbon nanotubes were modelled as space frame structures. The results showed that the critical buckling force depends on the dimensions of carbon nanotubes. The critical buckling forces of hetero-junction carbon nanotubes are in range between critical buckling forces of carbon nanotubes of both used diameters with the same chiralities without hetero-junction.

Published: May 2018

In this paper, results of numerical simulations and measurements are presented concerning the non-uniform torsion and bending of an angled members of hollow cross-section. In numerical simulation, our linear-elastic 3D Timoshenko warping beam finite element is used, which allows consideration of non-uniform torsion. The finite element is suitable for analysis of spatial structures consisting of beams with constant open and closed cross-sections. The effect of the secondary torsional moment and of the shear forces on the deformation is included in the local finite beam element stiffness matrix. The warping part of the first derivative of the twist angle due to bimoment is considered as an additional degree of freedom at the nodes of the finite elements. Standard beam, shell and solid finite elements are also used in the comparative stress and deformation simulations. Results of the numerical experiments are discussed, compared, and evaluated. Measurements are performed for confirmation of the calculated results.
Distorsion of Isochromatic Fringes in the Process of Stress Measurement in Structural Part by Photoelasticimetry
Authors: Frankovský Peter , Ostertag Oskar , Delyová Ingrid
Published: May 2018

In the article we show the possibility of distorting the results of the experiment by photoelasticity path, in case the isochromatic fringe patterns are recorded by the camera. The recording of the color spectrum may be distorted by inappropriate selection of the recording medium, which is reflected by different types of aberrations. Transferring a record to a computer allows you to automate the experiment process, thus saving time to work with isochromatic fringes. As an example, we present the experimental determination of the stresses of the rotor with a symmetrical arm. The analysis was performed using software developed by the authors. This software enables full automation of the experiment process. The rotor is investigated by the method of reflection photoelasticity. The experimental solution is realized as a case of periodically repeating dynamic effects, in which a stroboscopic source of white light is needed. The results of the experiment are compared with the numerical solution and their dependence is represented by diagram.

Authors: Szymańska Anna Irena , Płaziak Monika
Published: May 2018

Large shopping centres have become an important element of the urban landscape and a major competitor with other forms of retail sale. Their large offer, including a wide variety of products and services, special offers and tasting campaigns, large car parks, and own-brand fuel stations as well as various services points located in shopping centres successfully win customers.

The present study focuses on Polish shopping centres (malls), particularly those located in Krakow. A shopping centre (mall) is defined as “a commercial property designed, constructed and managed as a single business entity, comprising stores/shops and common areas, with a minimum leasable area of 5 thousand m2 (GLA) and accommodating at least 10 stores/shops”.

The purpose of this paper is to examine the behaviour of prospective customers of shopping centres, their preferences when selecting their shopping locations, and declarations on the use of additional functions offered by commercial and services enterprises. Furthermore, the paper identifies non-commercial functions of shopping malls of particular interest to prospective customers. The paper also presents a profile of a consumer who has a preference for shopping and spending their free time in malls.

The conclusions are based on literature on the subject and the findings of a survey conducted by the authors of the paper. A questionnaire was used as a research tool. The survey covered 1756 respondents – mainly residents of Krakow. In order to broaden the scope of the conclusions, the results of surveys and studies of other authors were also used.

Sensitivity analysis can be used to carry out hedging strategies. The sensitivity value measures how much the price change of the option influenced by some parameters. The aim of this study is to determine the sensitivity analysis of the buying price of European option by using the Greek method on Black Scholes Formula. From this study we get the values of delta, gamma, theta, vega, and rho. The values of deltas, gamma, vega, and rho are positive, which means that the value of the option is more sensitive than the corresponding parameter. The most sensitive value of gamma is obtained when the stock price approaches the strike price and approaches the expiry date. The value of theta obtained is negative and hence the most sensitive theta value is when the value is getting smaller. While, the most sensitive value of vega is obtained when the stock price is close to the strike price and is far from the expiry date. The most sensitive value of rho is obtained when the stock price gets bigger and farther from the expiry date.

Exploring Modular Glycolipids Involved in Nematode Chemical Communication
Authors: Von Reuss Stephan H.
Published: May 2018

Chemical communication in nematodes has been known for over half a century, but the underlying molecular basis remained largely elusive. Recent advances in analytical techniques facilitated the characterization of a modular glycolipid library based on the dideoxysugar L-ascarylose,
which modulates behavior and development in the model organism C. elegans. Ascaroside signaling is highly conserved in nematodes and represents a key factor in nematode chemical ecology. Ascaroside biosynthesis depends on the co-option of the peroxisomal ?-oxidation cycle and in
addition integrates a large diversity of additional building blocks derived from various primary metabolic pathways to give rise to species-specific modular assemblies, thus, transcending the concept of strictly segregated primary versus secondary metabolism.
The Three C's of Cethrene
Authors: Juríček Michal
Published: May 2018

Molecules that contain one or more unpaired electrons delocalized within a ?-conjugated backbone are promising candidates for applications in spin electronics or simply 'spintronics'. Our group develops functional organic materials based on ?-conjugated hydrocarbon molecules,
where the electrons are unpaired either in the ground state or in the excited state that is low in energy and can be populated thermally. We aim to learn how to introduce and control a multitude of properties, namely, optical, chiroptical, magnetic, and conductive, in a bulk material made
of these molecules, by manipulating spin interactions between the unpaired electrons. The first model system that was developed in our group is a hydrocarbon named cethrene, which has a diradicaloid singlet ground state and a low-lying triplet excited state. In this article, the structural
parameters and their impact on the properties and reactivity of cethrene are discussed within the realm of the three C's that symbolize cethrene's C-shape, chirality, and chameleonic reactivity.
Is Lewis Acidity in Metal Dications Triggered by Solvent Shell Fluctuations?
Authors: Stace Tony
Published: May 2018

Using experimental data collected on the stabilities of gas phase clusters consisting of metal dications in association with water molecules, a model is proposed to account for Lewis acidity. It is suggested that acidity is driven be fluctuations in the numbers of water molecules surrounding a metal ion, and that these fluctuations reduce numbers in the coordination shells to below those need to stabilise a +2 charge on the metal. The timescale on which these fluctuations are calculated to occur is approximately 6 orders of magnitude longer than any of the measure mean residence times of water molecules surrounding a central metal ion. This time difference reflects both the rarity of the event require to drive acidity and the extreme nature of some of the fluctuations.

Fuel cells efficiently convert chemical into electric energy, with promising application for clean transportation. In proton-exchange membrane fuel cells (PEMFCs), rare platinum metal catalyzes today the oxygen reduction reaction (ORR) while iron(cobalt)-nitrogen-carbon materials (Fe(Co)-N-C) are a promising alternative. Their active sites can be classified as atomically dispersed metal-ions coordinated to nitrogen atoms (MeNxCy moieties) or nitrogen functionalities (possibly influenced by sub-surface metallic particles). While their durability is a recognized challenge, its rational improvement is impeded by insufficient understanding of operando degradation mechanisms. Here, we show that FeNxCy moieties in a representative Fe-N-C catalyst are structurally stable but electrochemically unstable when exposed in acidic medium to H2O2, the main ORR byproduct. We reveal that exposure to H2O2 leaves iron-based catalytic sites untouched but decreases their turnover frequency (TOF) via oxidation of the carbon surface, leading to weakened O2 binding on iron-based sites. Their TOF is recovered upon electrochemical reduction of the carbon surface, demonstrating the proposed deactivation mechanism. Our results reveal a hitherto unsuspected deactivation mechanism during ORR in acidic medium. This study identifies the N-doped carbon surface as Achilles' heel during ORR catalysis in PEMFCs. Observed in acidic but not in alkaline electrolyte, these insights suggest that durable iron-nitrogen-carbon catalysts are within reach for PEMFCs if rational strategies minimizing the amount of H2O2 or reactive oxygen species (ROS) produced during ORR are developed.
A Fundamentação das Decisões Judiciais em Ações de Medicamentos no Contexto da Crise da Legalidade Burguesa
Authors: Rezende Ariadi Sandrini , Mansur João Paulo
Published: May 2018

O fornecimento de medicamentos gratuitos à população para o tratamento de enfermidades é regulamentado pelo decreto n° 7.508/2011, que criou a Relação Nacional de Medicamentos Essenciais - RENAME. Problema ocorre ao perguntar como os juízes devem proceder em ações de medicamentos que tenham como pedido fármacos não tabelados. Se faz necessário enfrentamento do dogma de que lei é lei e, por conseguinte, demonstração das exigências que o fenômeno jurídico contemporâneo exige das fundamentações de decisões sobre direitos sociais. Demonstra-se a ascensão da ideia de legalidade dentro do Estado burguês. São expostos três problemas que fundamentaram a crise desse modelo político de Direito. Explicita o processo de constitucionalização dos direitos sociais como reforma ao Estado liberal e, por conseguinte, como anseio de controle do poder político legislativo e da legalidade. Expõe como a atividade judicial pode consolidar a reforma iniciada pela constitucionalização dos direitos sociais ao ultrapassar empecilhos impostos contra sua efetivação. Demonstrado estará o anacronismo de decisões meramente legalistas que negam provimentos em ações de medicamento com base em dogmas do Estado liberal oitocentista. Expostas estarão as necessidades de decisões judiciais sérias que se perguntem sobre a função do Estado social e da atividade judiciária no contexto contemporâneo.

The Canadian Undergraduate Conference on Healthcare (CUCOH) has grown in its size and breadth of conference activities over the past 13 years, to become the largest undergraduate healthcare conference in Canada, which. It began at Queen’s University, in Kingston Ontario, with a clear need to bring together undergraduate students from diverse educational backgrounds to create a forum for healthcare knowledge exchange between experts in their fields and un-dergraduate students. The conference quickly grew in its programming to now host innovative training workshops, expert-led case challenges, and an expanding research competition program. It also grew in its size of students and experts, now welcoming over 400 students across 8 provinces in Canada, and over 50 experts to lead workshops, sem-inars, and judging of the research competition.
Over the next few sections, we hope to provide you with an understanding of the inner workings of CUCOH, the successes garnered and challenges faced, and advice we would give to future conference planners.

Sugar apple (Annona squamosa L.) is tropical climacteric fruit with a very short shelf life, ripening completely in just a few days under favorable conditions. Among the techniques employed to increase the time of conservation are the use of modified atmosphere and cooling. The objective of this work was to study the use of PVC film and cooling to increase the shelf-life time of fresh fruits of sugar apple. Fruits were harvested at the stage of physiological ripeness, stored in paperboard boxes (33cm x 27cm x 10cm) covered or not with PVC film and placed in refrigerators with temperatures set to 18ºC, 21ºC, 24ºC and room temperature (average 27°C±2). The experiment was set in a completely randomized design and the treatments evaluated in a fatorial scheme 2x4 (with and without PVC film and 4 temperatures) with four replications and three fruits per plot. The results showed that lower temperatures did not affect physical-chemical characteristics of the fruits, but increased the time of post-harvesting conservation by three fold. The use of PVC film helps to preserve the weight and the external and internal quality of the fruits, but it reduced the amount of total solid soluble of the fruit pulp on the consumption point.
