Spontaneous coronary artery dissection: challenges of coronary computed tomography angiography
Authors: Eleid Mackram F , Tweet Marysia S , Young Phillip M , Williamson Eric , Hayes Sharonne N , Gulati Rajiv 
Published: January 2017

Background: There is limited understanding of the role of cardiac computed tomography angiography (CCTA) for assessment of patients with spontaneous coronary artery dissection (SCAD). Methods: In this report we describe the diagnostic utility of CCTA in three young women presenting with signs and symptoms of myocardial ischemia who were eventually diagnosed with SCAD. Results: None of the women had traditional atherosclerotic risk factors. SCAD was not initially identified on CCTA in any of the three women, but was visualized during retrospective analysis in two patients after invasive coronary angiography. In two patients follow-up CCTA imaging was used successfully for subsequent management. Conclusions: In patients presenting with signs or symptoms of acute coronary syndrome, SCAD may be missed or not detectable on CCTA. A negative CCTA should not exclude a diagnosis of SCAD, and invasive coronary angiography should be considered for further evaluation.

Published: January 2017

Background: The aim of this study was to examine the value of predischarge exercise electrocardiogram (ECG) testing of chest pain patients in whom acute myocardial infarction (MI) had been ruled out by means of high-sensitivity troponins, ECG and history. Methods: All patients hospitalised for chest pain who underwent exercise ECG testing before discharge from the Department of Cardiology, Södersjukhuset, Stockholm, Sweden from January 2011 to June 2012 were included. Endpoints were death, MI and post-discharge revascularisation within 90 and 365 days, respectively. The background one-year risk of death and MI for a corresponding age, gender and calendar time-matched Swedish population was also examined. Results: A total of 951 patients were included. In 585 patients (61.5%) the exercise ECG test was negative, in 94 (9.9%) positive and in 272 (28.6%) inconclusive. There were no significant differences regarding death or MI between patients with a positive or a negative test, neither at 90 ( n=1 (1.1%) vs. n=1 (0.2%)) nor at 365 days ( n=2 (2.1%) vs. n=4 (0.7%)) of follow-up. In total there were nine (0.9%) deaths and 10 (1.1%) MIs within 365 days. The one-year rates of death (1.3%) and MI (0.5%) in a matched Swedish population were comparable. Conclusions: Predischarge exercise ECG testing after rule out of MI did not predict subsequent death or MI in a population of patients hospitalised for chest pain. Furthermore, the risks of death and MI in this population were comparable to a matched Swedish population. These findings suggest that patients could be discharged without this test.
Successful treatment of multifocal pedal Prototheca wickerhamii infection in a feline immunodeficiency virus-positive cat with multiple Bowenoid in situ carcinomas containing papillomaviral DNA sequences

Published: January 2017

Case summary A 16-year-old, castrated male, feline immunodeficiency virus (FIV)-positive, domestic shorthair cat developed multiple skin lesions. Most of these were Bowenoid carcinoma in situ and contained DNA sequences consistent with Felis catus papillomavirus type 2. Two additional lesions that developed in the skin and subcutaneous tissues between the digital and carpal pads on the left forelimb and right hindlimb were shown by cytology, histology and culture to be caused by Prototheca wickerhamii. These lesions failed to improve in response to systemic therapy treatment with itraconazole, but excision by sharp en bloc resection with follow-up oral itraconazole therapy proved curative for one lesion, although the other lesion recurred, necessitating a second surgery. Relevance and novel information This is only the second reported case of feline protothecosis from Australia and the first case that has been cultured and identified to the species level. Also of great interest was the presence of multiple papillomavirus-associated neoplastic lesions, which may have afforded a portal of entry for the algal pathogen and the cat’s positive FIV status; the latter might have impacted on both viral and algal pathogenesis by effects on immunocompetence.

Published: January 2017

Purpose: To evaluate the clinical results of rigid fixation of the greater trochanter fragment through a consecutive hemiarthroplasty series using a cementless and modular calcar-replacement prosthesis with an integrated plate (MOD-Centaur stem) with 1-year follow-up in very elderly patients with unstable intertrochanteric fractures. Methods: We assessed 44 consecutive very elderly patients (age >85 years; 2 men, 42 women; mean age at surgery: 89.6 years) with an unstable intertrochanteric fracture who underwent bipolar hemiarthroplasty using the MOD-Centaur stem by the same surgeon. Operative time and blood loss were evaluated, and postoperative complications and mortality rate within 1 year were assessed. Bony union of the greater trochanter was evaluated using plain X-ray images at least 6 months postoperatively. Walking ability was evaluated at the time of discharge and at 1 year postoperatively. Results: The mean operative time was 95.8 min, and the mean intraoperative blood loss was 358.0 mL. Postoperative peripheral infection occurred in one patient. Four patients died within 1 year postoperatively (mortality rate: 9.1%). Bony union of the greater trochanter was achieved in all the patients who had a plain X-ray taken at least 6 months postoperatively. At 1-year follow-up, 20 patients could walk independently. Conclusion: Hemiarthroplasty using the MOD-Centaur stem for unstable intertrochanteric fracture in very elderly patients offers favorable outcomes. These findings encourage early walking without any loading limitations, despite severe osteoporosis, and emphasize the importance of greater trochanteric fixation, which reconstructs the mechanism of the gluteus medius muscle.
Multiligament Injury of the Knee. First Intrarticular or Posterior
Authors: Calderón Nils 
Published: January 2017

Objectives: Show our experience about the multiligament injury of the knee. In the surgical technique it is most popular and recommended stabilized first all posterior and lateral (Ligament cruciate Posterior (LCP) and postero-lateral corner) if is a case. We show our experience stabilized first all intra-articular ACL and LCP. Methods: Prospective study and Case Series. The study includes, 45 cases in 15 years of experience. The patients have two or more ligaments with rupture, and associated lesions, like meniscus, cartilages, fractures, etc. 45 cases with a ACL rupture, 40 PCL, 7 posteromedial corner, 25 postero-lateral corner, 30 meniscus medial, 28 meniscus lateral, 1 vascular lesion, and 3 fibular nerve. In the surgical technique always use autograft. Prefer hamstrings, quadricipital tendon, contralateral hamstrings, BTB and sometimes peroneus brevis. We hope 1 or 2 weeks for the surgery. I never use pump, and use tourniquet for two hours. We start for the meniscus lesions and cartilage lesion and first reconstruction ligaments intra-articular. Finalized we open the tourniquet and stabilized the postero-lateral o posteromedial corner if is necessary. In the first cases we did a surgery in two times, but now we stabilized in one surgical time. Results: 3 to 6 days in the hospital 2 weeks immobilized and star rehabilitation with brace for more two weeks. Use crutches for 4-6 weeks. Worked in rehabilitation for a one year and star competition in one year. Complications: 1 case of amputation for vascular lesion, 9 arthrofibrosis, 2 medial instability, 1 lateral instability and1 LCP instability. One case needs a revision two years after the first surgery, for a new trauma in the work. All other cases had a new surgery for revision the residual instability. Conclusion: The multiligament injury of the knee it is not frequently, but every year I receive more cases, and more difficult. In the surgical technique have two options. The more recommended stabilized first all posterior (LCP and postero-lateral corner). Our experience shows no difference in these two options.

Published: January 2017

Introduction: In cases of patients with ligament hiperlaxity with rupture of ACL, the use of a BTB graft is recommended for its reconstruction. Our job consists of the clinical and functional assessment of a group of 10 patients with ligament laxaty according to Beighton scale, who, after surgery for ACL rupture with BTB technique, suffered a rupture of the plastic. For its reconstruction a combination of intra-articular and extra-articular techniques was used with a BTB graft in the contralateral knee, associated with a modified Lemaire technique. Methods: The series consists of 10 patients, male, average age of 24.2 years, amateur athletes, operated for a second time in March, 2011 and November, 2013, with a minimum follow-up of 24 months. They were evaluated before surgery and 24 months after surgery based on Lysholm scale, IKDC evaluation form and a physical exam (Lachman - Pivot Shift). Results: After surgery, the average in Lysholm scale was of 87.6 and 86.3 for the IKDC subjetive form. In the physical exam, 8 patients showed Lachman 1+, while none of the patients showed Pivot Shift positive. 7 patients were able to return to their usual sport activities. As a postoperative disadvantage, 6 patients reported pain in the external face of the knee in the first 6 months. And 4 patients reported a subjetive loss of full extension that did not interfere with their sport activities. Conclusion: Based on our experience and literature, we believe that the combination of both techniques, intra-articular (BTB) and extra-articular (Lemaire), is a good alternative for patients with ligament laxaty, providing positive clinical and functional results.
Geoelectric prospecting in University Campus region for detection of possible geological discontinuities, Rio, Patra, Greece.

Published: January 2017

Geophysical prospecting is a non catastrophic technique, applicable on a wide range of problems, including archaeological, environmental and geological problems. At Campus University of Patras, a detailed geophysical investigation applied for detection of possible existing geological discontinuities, which produced serious problems at buildings and main roads of Campus. As main technique used the electric mapping and electric imaging. These were applied on already prepared geophysical grids by measuring parallel profiles along and perpendicular to the geomagnetic north. The two geophysical grids were separated 100 meters away each other. Firstly, an electric mapping procedure took place by using twin-probe array with four electrodes in distance between 0.5-3 meters. As result was the recording of soil resistance on horizontal layer with constant depth. By processing the data through Geosoft Oasis Montaj software, the distribution of this physical property was illustrated on color scale maps. Secondly, electric imaging technique applied with twenty-five equal space electrodes along straight lines, with one meter space byusing the hybrid arrangement Wenner-Schlumberger (Stephanopoulos, 2002). As result was the recording of distribution of soil apparent resistivity on a vertical layer in eight separated depths. Resistivity calculated by processing imaging data through 2D mathematical algorithm based on least squares inversion (Res2Dinv). Furtherprocessing by Oasis Montaj, had as a result the production of horizontal slices (Stephanopoulos 2002) and 3D maps, where the resistivity distribution was illustrated on separated depths, in color and grey schedule format. The combined geophysical investigation with the contribution of the HVSR (Horizontal to Vertical Spectral Ratio) technique confirmed the existence of geological discontinuity.

The present study deals with the groundwater investigation of hydrogeological conditions of Southern Rhodes, in the search for additional groundwater supplies to support the water needs of the area. An extensive Hydrogeological – Geophysical research was conducted, aimed to identify exploitable groundwater zones. Thisgeophysical survey was carried out along alluvial basins, looking for more permeable geological formations within the sequence of the Neogene and Quarternary deposits. The use of a high resolution geophysical method (ERT) was selected for targeting the shallow geological structures and hydrostratigraphy. Thirteen ERT sections of total length of approximately 34000m were measured, laid out primarily at the south eastern part of the island. The geophysical survey revealed that alluvial sediments have an average thickness of about 30m while nearby the coastal zone increase locally up to 50m. The hydrostratigraphical structure is characterized by three distinct sections, the overlying alluvial deposits, the intermediate clay-marls and the underlying coarse formations. Moreover, almost all fault zones which are reflected in the surface geological map are revealed ingreater depths. Result of vertical tectonic movements is the uplift of geological formations with increased resistivity. Finally, the target areas were selected based on hydrogeological criteria and specifically taking into account the increased possibility of groundwater reservoirs within the alluvial aquifer.

We present the structure and first results of the "Thales" project on site classification in Greece. The aim of the project is twofold: to develop and present a methodology for the characterization and classification of site conditions based on their geological, geomorphological and geophysical characteristics and to apply the proposed methodology to case studies in Greece, including the urban areas of Xanthi, Edessa and Grevena. In particular, the units described on a surficial geological map will be correlated to shear-wave velocity data, corresponding to the upper 30m (Vs30) of the soil column, aiming to produce first order maps to help practitioners and provide the tools to realistically predict ground motions triggered by an earthquake. The classification will be based on information provided by borehole logs, where velocity profiles were measured and will be validated using the three case studies. The outcome of the project will be usable by national agencies and decision makers for urban planning.
Οι Δημοκρατικές Γιορτές της Γαλλικής Επανάστασης και η Ελληνική Αρχαιότητα
Authors: Menegaki Kintis Maria 
Published: January 2017

Οι δημοκρατικές γιορτές ήταν ένας νέος θεσμός που λειτούργησε στη Γαλλία από το 1789 ώς το τέλος του ι800. Πρόκειται για ένα σύστημα δημόσιων τελετών συνδεδεμένων με τη νέα «πολιτική θρησκεία» η οποία αντικατέστησε," για ένα διάστημα, το καθολικό δόγμα και τις τελετουργίες του. Σκοπός τους ήταν η διάδοση των νέων αξιών που είχαν διατυπωθεί από το κίνημα του Διαφωτισμού, και πρότυπο τους οι δημόσιες τελετουργίες της αρχαίας Ελλάδας, ο χαρακτήρας των οποίων ανταποκρινόταν απόλυτα στα οράματα της επαναστατικής αστικής τάξης. Η ηθοπλαστική τους αξία είχε εξαρθεί τόσο από τον J.-J. Rousseau, μελετητή και θαυμαστή του Πλούταρχου, όσο και από τον Abbé Barthélémy, συγγραφέα του έργου Το Ταξίδι τον Νεαρού Ανάχαρση στην Ελλάδα, στο μέσο του 4ον> π-%- Αιώνα (1788).Η προσπάθεια αυτή της Γαλλικής Επανάστασης να εκριζώσει τις χριστιανικές καταβολές του γαλλικού πολιτισμού οδήγησε στην καθιέρωση, από την Convention, της θρησκείας του Υπέρτατου Όντοςκαι του εορτολογίου της. Ο μεγαλειώδης εορτασμός της εορτής του Υπέρτατου ' Οντος στο Παρίσι και σε όλες τις κοινότητες της χώρας, στις 20 πραιριάλ του δεύτερου έτους της Δήμοκρατίας, ήταν το αποκορύφωμα της επιστροφής στην αρχαιότητα. Ο θεσμός των δημοκρατικών γιορτών είναι ένα πρωτοφανές φαινόμενο για τον γαλλικό και τον ευρωπαϊκό πολιτισμό. Χάρη σ' αυτόν πλατιά στρώματα του γαλλικού λαού μυήθηκαν στις αξίες του αρχαίου ελληνικού πολιτισμού, που ήταν ώς τότε προνόμιο μιας ολιγάριθμης ελίτ λογίων και ανθρώπων των γραμμάτων. Σήμερα, στην αυγή του 2ΐου αιώνα, όπου ταφαινόμενα θρησκευτικού φανατισμού πληθαίνουν και θέτουν σε κίνδυνο τις ανθρώπινες ελευθερίες, βλέπουμε τον ουνιβερσαλισμό της γαλλικής σκέψης, θρεμμένης με την αρχαία ελληνική κληρονομιά, ως μια από τις σημαντικότερες όψεις της Γαλλικής Επανάστασης.
Confianza en la policía en Chile: un arma de doble filo
Authors: Dammert Lucia 
Published: January 2017

Carabineros es una de las policías mejor evaluadas en América Latina. Una de sus características es la positiva evaluación ciudadana que la instala como la institución con mayor nivel de confianza. Sin embargo este elemento también ha limitado la intervención política sobre los procesos institucionales e inhibido las reformas que emanan de actores sociales y políticos en áreas que requieren ser revisadas. El artículo describe el proceso chileno marcado por niveles de criminalidad estables, creciente temor, alta preocupación por el delito y baja evaluación de los actores del sistema. Paradojalmente, la institución policial parece no ser afectada por el panorama de molestia y preocupación ciudadana, por el contrario es calificada positivamente. También el documento muestra que el indicador de confianza debe ser analizado con mayor detalle y focalizar en aquellos grupos que muestran más desconfianza e insatisfacción en el trabajo policial: pobres, jóvenes y aquellos que han tenido contacto con funcionarios policiales.

Published: January 2017

AbstractA new series of low-melting, highly volatile, thermally and air-stable cadmium MOCVD precursors have been synthesized and characterized. Cd(hfa)2(N, N-DE-N', N'-DMEDA) has been successfully utilized in the growth of highly conductive and transparent CdO thin films. Hall measurements conducted on films deposited simultaneously on MgO (100) single crystal and Corning 1737F glass substrates reveal that the films on MgO have significantly enhanced carrier mobilities. Owing to similar grain sizes and carrier concentrations we attribute this effect to improved texture and associated improvements crystalline order. Conductivities as high as 8,590 S/cm are obtained which is to our knowledge the highest value reported to date for CdO films without aliovalent dopants.

AbstractThe thermal stability of nanocrystalline ultra-soft magnetic (Fe98Zr2)1-xNx films with x=0.10-0.25 was studied using high-resolution transmission electron microscopy (HRTEM), positron beam analysis (PBA) and thermal desorption spectrometry (TDS). The results demonstrate that grain growth during the heat treatment is accompanied by an increase of the free volume, by nitrogen reallocation and desorption. All this can drastically deteriorate the ultra-soft magnetic properties. The desorption starts already at slightly elevated temperatures, below 100°C. However, most of the nitrogen leaves the sample at a temperature above 500°C.

Published: January 2017

Background: SLE is an autoimmune disease most frequently found in women of child bearing age and may co­exist with pregnancy. Its multisystem involvement and therapeutic interventions pose a high risk for both the mother and the foetus. Disease flares in pregnancy pose challenges with respect to distinguishing physiologic changes related to pregnancy from disease related manifestations. The present study analyzes the fetomaternal outcome of pregnant women with SLE.Methods: An analysis of fetomaternal outcome of pregnant women with SLE during April 2015 to May 2016 at JSS hospital.Results: During the period from April 2016 to May 2016, 3773 deliveries were conducted in the department. Eleven pregnant women with SLE were followed up during this period, giving an incidence of 0.29/1000 deliveries. A high rate of lupus flare during pregnancy was found in the current study. Even among women in remission for more than six months before pregnancy, the rate of lupus flare was not low (27%). Also other complications seen were pre-eclampsia 54.54%, HELLP syndrome in 9.09% , PPH in 50%, polyserositis seen in 9.09% and one maternal death was seen (9.09%). No neonate suffered from heart-blocker however there was 75 % NICU admissions among live borns.Conclusions: Advancing technology and better understanding of the maternal-foetal relationship in lupus have improved outcomes in lupus pregnancies over the last decade. The multisystem nature of the disease, the severity of the organ involvement needs to be assessed and a multidisciplinary approach is required for its diagnosis and successful management.

Karimata strait and the java sea is one of the most densely shipping lanes in the maritime country of Indonesia. Information of a significant wave is needed to safety navigation. The prediction of a significant wave mostly employs the modeling using wind as input data to produce an early warning warning prediction. Characteristic of a significant wave shows the maximum wave height in the strait and the java sea karimata occurs in west monsoon (January) and east season (August) every year. Especially at the peak of west monsoon (January) maximum wave height reach 1.5-3 meters in Karimata Strait, and reach 0.5-2.5 meters in Java Sea. The frequency of significant wave occurences mostly extend until February, where wave height in Java Sea will stay the same (0.5-2.5 meters), while in Karimata Strait is little bit decrease (1-2.5 meters). Recommended to all sea transportation users, in those regions during January and February, to avoid using ship with the hull is less than 3 meters height.Keywords: significant wave characteristic, Karimata Strait, Jawa Sea, Wind, Modeling
