The impact of the EHEA in the professsional internships: Interviews with the academic coordinators
Authors: Alemany Josepa , Perramon Xavier , Panadès-Estruch Laura 
Published: March 2016

Purpose: This paper presents a study of the professional internship models in each Faculty at the Universitat Pompeu Fabra (UPF) of Barcelona, Spain; their relationship to the idiosyncrasy of each type of studies, and their evolution from 2009, before the European Higher Education Area (EHEA), until the 2013-2014 academic year. This study is part of a larger project that comprises the point of view of the three agents involved in the internships: students, academic tutors and in-company tutors. Design/methodology/approach: This paper provides the data obtained from one of the three agents involved, namely the academic supervisor-tutors. We present the methodology used to compile the data before and after EHEA implementation: firstly, by means of deep individual and face-to-face interviews, and in a second stage by means of e-surveys, jointly with quantitative and objective data related to the internships activity during the period of the study. Findings: Following the conclusion of the first part of the study related to the internships before the EHEA, we found four different models of monitoring and assessing the internships; we anticipated the four models would converge into two, and eventually into one. The final model expected was focused on more intensive monitoring. In the second part of the study, even though we found fewer changes in the models than we expected, the impact of the EHEA deployment has been very important in quantitative aspects and in the breadth of the changes. Also, for some Faculties, the internship has become one of the most important subjects of the curricula. Originality/value: This is the first study of the EHEA impact on the professional internships in a Spanish University.

Abstract
Background: It is of significant importance to assess the extent of hepatic steatosis in living donor liver transplant (LDLT) surgery to ensure optimum graft regeneration as well as donor safety. Aim: To establish the accuracy of non-invasive imaging methods including computed tomography (CT), dual-echo in- and opposed-phase magnetic resonance imaging (MRI), and MR spectroscopy (MRS) for quantification of liver fat content (FC) in prospective LDLT donors with histopathology as reference standard. Settings and Design: This retrospective study was conducted at our institution on LDLT donors being assessed for biliary and vascular anatomy depiction by Magnetic Resonance Cholangiopancreatography (MRCP) and CT scan, respectively, between July 2013 and October 2014. Materials and Methods: Liver FC was measured in 73 donors by dual-echoT1 MRI and MRS. Of these, CT liver attenuation index (LAI) values were available in 62 patients. Statistical Analysis: CT and MRI FC were correlated with histopathological reference standard using Spearman correlation coefficient. Sensitivity, specificity, positive predictive value, negative predicative value, and positive and negative likelihood ratios with 95% confidence intervals were obtained. Results: CT LAI, dual-echo MRI, and MRS correlated well with the histopathology results (r = 0.713, 0.871, and 0.882, respectively). An accuracy of 95% and 96% was obtained for dual-echo MRI and MRS in FC estimation with their sensitivity being 97% and 94%, respectively. False-positive rate, positive predictive value (PPV), and negative predicative value (NPV) were 0.08, 0.92, and 0.97, respectively, for dual-echo MRI and 0.03, 0.97, and 0.95, respectively, for MRS. CT LAI method of fat estimation has a sensitivity, specificity, PPV, and NPV of 73%, 77.7%, 70.4%, and 80%, respectively. Conclusion: Dual-echo MRI, MRS, and CT LAI are accurate measures to quantify the degree of hepatic steatosis in LDLT donors, thus reducing the need for invasive liver biopsy and its associated complications. Dual-echo MRI and MRS results correlate better with histological results in the study, as compared to CT LAI method for fat quantification.

Published: March 2016

Abstract
Objective: To evaluate patients who had undergone pyeloplasty for pelviureteric junction obstruction, by measuring the anteroposterior diameter (APD) of the renal pelvis in supine and prone positions, and determine whether a decrease in APD in prone position can exclude obstruction in dilated renal system. Materials and Methods: From January 2012 to December 2013, patients who had undergone pyeloplasty were evaluated by ultrasound in two centers. The difference of APD of the renal pelvis in supine and prone positions was obtained. Correlation was made with the pre- and post-pyeloplasty renal function by radionuclide renogram. Results: There were 42 patients (31 males, 11 females; age range 5 months to 18 years). Residual hydronephrosis was detected in 41 patients of whom 35 patients (85%) showed decrease in APD by &gt;10% in prone position. These patients and the one without hydronephrosis showed either no deterioration or improvement in renal function. Six patients (15%) showed either no change or increase in APD in prone position. Three patients (7.5%) were confirmed to have decrease in renal function indicating obstruction. Three patients (7.5%) showed no deterioration of renal function, but sluggish drainage on radionuclide renogram. Conclusion: Demonstration of decreased APD of renal pelvis in prone position by ultrasound is useful to differentiate obstructed from non-obstructed dilated renal system, and it correctly identified 85% candidates with successful pyeloplasty. In patients with no decrease or increase in APD at prone position, further follow-up is recommended to rule out obstruction.

AbstractCranial nerve thickening as an initial isolated presentation of CNS lymphoma is rare. Once an extremely rare neoplasm, primary lymphoma of the central nervous system (CNS) now ranks  only next to meningiomas and low-grade astrocytomas in prevalence. Multiple cranial nerve thickening can be a feature of primary CNS lymphoma. Here we report a case of a 45-year-old immunocompetent female who presented with relapsing remitting multiple cranial nerve thickening as an initial feature of primary CNS lymphoma without any other brain or spinal cord lesions.

ABSTRACT
Objective: Comprehensive diagnosis and treatment planning are essential in a successful orthodontic practice. The purpose of this study is to determine and compare intermaxillary tooth size discrepancy (IMTSD) using traditional digital caliper (DC) measurement on plaster dental models and stereomicroscopic digital dental models (SM). Materials and Methods: The samples were randomly selected from different states of Pakistan. Total 7168 variables were measured on plaster dental casts (128) and SM digital dental models (128) according to the selection criteria. For IMTSD, the 6 variable measured as for anterior tooth size (maxilla, mandibular), overall tooth size (maxilla, mandibular), Bolton's anterior ratios (BAR), and Bolton's overall ratios (BOR). The independent t-test and ANOVA were used for statistical analyses. Results: Significant sexual disparities in the sum of anterior tooth size and overall tooth size via DC and SM methods. No significant sexual disparities for BAR and BOR. No statistically significant differences were found in BAR and BOR between DC and SM. No significant differences were found on IMTSD ratio among different arch length and arch perimeters groups. Conclusions: Norms were developed based on DC and SM for IMTSD. Sexual disparities were observed in the sum of teeth size. However, no significant differences in BAR and BOR for IMTSD between the two methods.

Published: March 2016

ABSTRACTThe aim of this review was to investigate usage of computer-aided design/computer-aided manufacture (CAD/CAM) such as milling and rapid prototyping (RP) technologies for removable denture fabrication. An electronic search was conducted in the PubMed/MEDLINE, ScienceDirect, Google Scholar, and Web of Science databases. Databases were searched from 1987 to 2014. The search was performed using a variety of keywords including CAD/CAM, complete/partial dentures, RP, rapid manufacturing, digitally designed, milled, computerized, and machined. The identified developments (in chronological order), techniques, advantages, and disadvantages of CAD/CAM and RP for removable denture fabrication are summarized. Using a variety of keywords and aiming to find the topic, 78 publications were initially searched. For the main topic, the abstract of these 78 articles were scanned, and 52 publications were selected for reading in detail. Full-text of these articles was gained and searched in detail. Totally, 40 articles that discussed the techniques, advantages, and disadvantages of CAD/CAM and RP for removable denture fabrication and the articles were incorporated in this review. Totally, 16 of the papers summarized in the table. Following review of all relevant publications, it can be concluded that current innovations and technological developments of CAD/CAM and RP allow the digitally planning and manufacturing of removable dentures from start to finish. As a result according to the literature review CAD/CAM techniques and supportive maxillomandibular relationship transfer devices are growing fast. In the close future, fabricating removable dentures will become medical informatics instead of needing a technical staff and procedures. However the methods have several limitations for now.

ABSTRACT
Objective: The aim of this study was to compare cephalometric variables of subjects with normal and cesarean births. Materials and Methods: Ninety age- and gender-matched patients, who were treated in Gaziantep University, Faculty of Dentistry Orthodontics Department were equally divided into normal and cesarean groups according to the birth methods reported by their mothers. To eliminate the negative effects of being different in terms of age and gender among parameters, control, and patient groups were matched in the present study. Pretreatment cephalometrics radiographs were used. Six measurements representing sagittal and vertical relationships were evaluated from pretreatment cephalograms using Dolphin Imaging Orthodontics Software was used in this issue by an orthodontist. Kolmogorov–Smirnov test, Student's t-test, and Mann–Whitney U-test were used for statistical comparisons. Results: A point-nasion-B point angle (ANB) and Wits values were higher in the normal group, while sella-nasion-A point angle, sella-nasion-B point angle, Frankfort horizontal-mandibular plane angle, and gonion-gnathion-SN plane angle values were higher in the cesarean group. However, the groups showed no significant differences (P > 0.05). ANB angle and Wits values showed high correlation. Conclusions: Within the study limitations, the results suggest that the birth method may not have a considerable effect on the development of the craniofacial skeletal system.

ABSTRACT
Objective: In this paper, cavity experiences of children with different levels of eruption and cavity activities that are enrolled at an elementary school with semi-rural characteristics in Kırıkkale Provincial center were monitored for 2 years after a variety of protective applications. Materials and Methods: Three hundred and twenty-two children at the age of 7–11 were included in this study. Children were grouped as follows according to their cavity experiences and applications done: Group 1 - control group (with or without cavities) – was given hygiene training only; Group 2 - with medium level cavity activity (2–4 cavities in average) – oral hygiene training + surface restoration applied; Group 3 - children with 2–4 cavities on average – oral hygiene training + professional flour gel applied; Group 4 - children with 2–4 cavities in average – oral hygiene training + flour gel applied with brush; Group 5 - children with extreme cavity activity (children with 5 or more cavities) – oral hygiene training + surface restoration + professional flour gel combination applied. Results: At the end of the 2nd year, 277 children were reached. The increase of number of cavities in permanent teeth was determined as 35%, 0%, 1%, 0%, and 7% in groups 1–5, respectively. The difference between groups was found to be significant (Chi-square analysis, Pearson Chi-square = 27.002, P < 0.01). Conclusion: These findings have showed that, in Kırıkkale Provincial center, some cavity-preventive measures such as surface restoration and gel applications, along with hygiene training, could provide optimum protection for school-age children.

Published: March 2016

ABSTRACT
Objective: The aim of this study was to evaluate the effect of increased exposure time and light intensity on microhardness of cured composite through different thicknesses of tooth structure in primary teeth. Materials and Methods: One hundred and seventy cylindrical resin composite specimens were prepared. All specimens were divided into 17 experimental and control groups. “Light-emitting diode” light curing unit (LCU) applied directly or through 1, 2, and 3 mm thicknesses tooth slices for experimental groups. The irradiation protocols were 25 and 50 s at 650 mW/cm2 and 15 and 30 s at 1100 mW/cm2. The “quartz-tungsten-halogen” LCU (400 mW/cm2) for 40 s was used in control group. Microhardness was measured by the Vickers hardness test. Results: Indirectly cured specimens and those cured through a 1 mm thick tooth structure, an increase in intensity caused hardness drop. In the specimens cured through 2 and 3 mm thick tooth structures, increased intensity and/or exposure time did not show any appropriate changes on microhardness. Conclusion: Irradiation through a 1.0 mm thick tooth slice resulted in reduced microhardness although it was still within the clinically acceptable level. The hardness values of the specimens cured through 2 or 3 mm thick tooth slices fell below the clinically acceptable level even after doubling the exposure time and/or light intensity.

Published: March 2016

ABSTRACT
Objective: The purpose of this paper was to describe the prevalence and type of dental anomalies in the primary and permanent dentition in children with a cleft condition at Princess Margaret Hospital in Perth, Western Australia. Materials and Methods: The details of 162 current dental patients extracted from the main dental database through their year of birth for the period 1998–2001 were selected consecutively. Dental records and X-rays were examined by one examiner (WN) and verified by a second examiner (RB) to determine dental development. The mean age of the subjects was 10.8 years with equal numbers of males and females. Subjects were further divided into cleft type; unilateral cleft lip (UCL) and palate, bilateral cleft lip (BCL) and palate, UCL, BCL, and cleft palate. Results: One hundred sixty-two subjects were grouped into 21 categories of anomaly or abnormality. Prevalence rates for the categories were calculated for the overall group and for gender and cleft type. Conclusion: Overall, 94% of patients were found to have at least one dental anomaly, with fifty-six (34%) patients having more than one anomaly or abnormality.

Published: March 2016

ABSTRACT
Objectives: The aim of this study was to evaluate dentine permeability after brushing with Twin Lotus®, Thai herbal toothpaste by comparing with Sensodyne Rapid Relief®, a commercial desensitizing toothpaste, and also after artificial saliva (AS) immersion or citric acid challenge. Materials and Methods: Dentine discs from human mandibular third molars were divided into three groups (n = 20) and brushed with either experimental toothpaste or water (control) for 2 min with an automated toothbrush. Then, 10 discs were immersed in AS, and the other 10 discs were immersed in 6% citric acid to simulate the conditions of the oral environment. The dentine permeability of each specimen was measured before brushing and after each treatment using a fluid filtration system. Morphological changes in the dentine were observed using scanning electron microscopy (SEM). Results: Both toothpastes significantly reduced dentine permeability, and a crystalline precipitate was observed on the dentine surface under SEM observation. No significant difference was found between the two toothpaste groups with regard to dentine permeability after brushing and AS or acid immersion. Conclusions: The dentine permeability reduction caused by the two toothpastes did not differ after brushing or after AS or citric acid immersion.

Published: March 2016

Primary percutaneous coronary intervention (P-PCI) has become the preferred reperfusion strategy in ST-elevation myocardial infarction (STEMI) when performed by an experienced team in a timely manner. However, no consensus exists regarding the management of multivessel coronary disease detected at the time of P-PCI. Aim The aim of this study was to evaluate the use of the residual SYNTAX score (rSS) following a complete vs. culprit-only revascularization strategy in patients with STEMI and multivessel disease (MVD) to quantify the extent and complexity of residual coronary stenoses and their impact on adverse ischemic outcomes. Methods Between October 1, 2012, and November 30, 2013, we enrolled 120 consecutive STEMI patients with angiographic patterns of multivessel coronary artery disease (CAD) who had a clinical indication to undergo PCI. The patients were subdivided into those who underwent culprit-only PCI (60 patients) and those who underwent staged-multivessel PCI during the index admission or who were staged within 30 days of the index admission (60 patients). Both the groups were well matched with regard to clinical statuses and lesion characteristics. Clinical outcomes at one year were collected, and the baseline SYNTAX score and rSS were calculated. Results The mean total stent length (31.07 ± 12.7 mm vs. 76.3 ± 14.1 mm) and the number of stents implanted per patient (1.34 ± 0.6 vs. 2.47 ± 0.72) were higher in the staged-PCI group. The rSS was higher in the culprit-only PCI group (9.7 ± 5.7 vs. 1.3 ± 1.99). The angiographic and clinical results after a mean follow-up of 343 ± 75 days demonstrated no significant difference in the occurrence of in-hospital Major Adverse Cardiac and Cerebrovascular Events (MACCE) between both the groups (6.7% vs. 5%, P = 1.000). However, patients treated with staged PCI with an rSS ≤8 had significant reductions in one-year MACCE (10.7% vs. 30.5%, P = 0.020*), death/Myocardial infarction (MI)/Cerebrovascular accident (CVA) (5% vs. 13.8%, P = 0.016*), and repeat revascularization (4.8% vs. 25%, P = 0.001*). We found that culprit-only, higher GRACE risk scores at discharge and an rSS >8 were independent predictors of MACCE at one year. Conclusions Staged PCI that achieves reasonable complete revascularization (rSS ≤8) improves mid-term survival and reduces the incidence of repeat PCI in patients with STEMI and MVD. Nonetheless, large-scale randomized trials are required to establish the optimal revascularization strategy for these high-risk patients.
