Authors: Kumar Ishan , Verma Ashish , Ojha Ritu , Aggarwal Priyanka 
Published: January 2017

AbstractWe report two infants presenting with unilateral congenital facial palsy since birth. Magnetic resonance imaging (MRI) in both the cases revealed complete unilateral aplasia of facial nerve. To our knowledge, this is the first reported MR depiction of nonsyndromic isolated facial nerve aplasia. Imaging features and the pertinent anatomy is discussed along with a brief review of literature.
Pitfalls in interpretation of FDG PET/CT: Septic pulmonary emboli mimicking metastases in a case of gastric carcinoma

Published: January 2017

AbstractInflammatory lesions may sometimes show intense tracer uptake and mimic neoplastic lesions on (18) F-fluoro-deoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). We report one such false positive case on FDG PET/CT, where septic pulmonary emboli (SPE) mimicked pulmonary metastases. A 45-year-old man with stomach cancer had an indwelling central venous catheter (CVC) in situ while on neoadjuvant chemotherapy. He underwent FDG PET/CT scan for response assessment and the images revealed multiple, intensely FDG avid, peripheral, lung nodules with feeding vessels, which were suspicious for pulmonary metastases. A day later, the patient developed fever with chills and his blood culture showed bacterial growth (Enterobacter cloacae). A provisional diagnosis of SPE from an infected CVC was made. Chemotherapy was withheld, CVC removed, and the catheter tip was sent for bacterial culture. Following a 4-week course of antibiotic treatment, the patient became afebrile. Culture from the CVC tip grew the same organism, as was seen earlier in the patient's blood culture, thus pin-pointing the source of infection in our case. Diagnosis of SPE was clinched when follow-up CT chest done after completion of antibiotic course showed complete resolution of the lung lesions.
Accuracy of MRI for prediction of response to neo-adjuvant chemotherapy in triple negative breast cancer compared to other subtypes of breast cancer
Authors: Bansal Gaurav J , Santosh Divya 
Published: January 2017

Abstract
Purpose: The aim of this study was to compare the accuracy of magnetic resonance imaging (MRI) for the prediction of response to neo-adjuvant chemotherapy in triple negative (TN) breast cancer, with respect to other subtypes. Materials and Methods: There were a total of 1610 breast cancers diagnosed between March 2009 and August 2014, out of which 82 patients underwent MRI before and after neo-adjuvant chemotherapy but just before surgery. TN cancers were analyzed with respect to others subtypes. Accuracy of MRI for prediction of pathological complete response was compared between different subtypes by obtaining receiver operating characteristic (ROC) curves. The Statistical Package for the Social Sciences version 21 was used for all data analysis, with P value of 0.05 as statistically significant. Results: Out of 82 patients, 29 were luminal (HR+/HER2−), 23 were TN (HR−, HER2−), 11 were HER2 positive (HR−, HER2+), and 19 were of hybrid subtype (HR+/HER2+). TN cancers presented as masses on the pre-chemotherapy MRI scan, were grade 3 on histopathology, and showed concentric shrinkage following chemotherapy. TN cancers were more likely to have both imaging and pathological complete response following chemotherapy (P = 0.055) in contrast to luminal cancers, which show residual cancer. ROC curves were constructed for the prediction of pathological complete response with MRI. For the TN subgroup, MR had a sensitivity of 0.745 and specificity of 0.700 (P = 0.035), with an area under curve of 0.745 (95% confidence interval: 0.526–0.965), which was significantly better compared to other subtypes. Conclusion: TN breast cancers present as masses and show concentric shrinkage following chemotherapy. MRI is most accurate in predicting response to chemotherapy in the TN group, compared to others subtypes. MRI underestimates residual disease in luminal cancers.

Published: January 2017

Abstract
Introduction: The objective of our study was to review the results of percutaneous angioplasty (PTA)/stenting in the treatment of patients who presented with symptoms and angiographic findings of chronic mesenteric ischemia (CMI). Materials and Methods: We performed a retrospective analysis of 13 consecutive patients from a single institution who underwent PTA/stenting for the treatment of symptoms suggestive of CMI. Results: All 13 patients in our study were men, and most common presenting symptoms were weight loss and postprandial pain. Atherosclerosis was the most common cause. PTA and stenting was performed in 9 patients and PTA alone was done in 4 patients. Primary technical success rate was 92% with complete resolution of symptoms within 2 weeks in all patients. No statistical difference was noted in primary clinical success rate based on the number of vessels treated or the method of treatment. However, in patients whom SMA was treated had longer duration of symptom-free survival as compared to other vessels. Conclusion: PTA and stenting are very effective therapeutic options for patients presenting with CMI symptoms. It should be considered as the first-line of management in such patients.
Restricted diffusion in the corpus callosum: A neuroradiological marker in hypoxic–ischemic encephalopathy
Authors: Kale Alok , Joshi Priscilla , Kelkar A 
Published: January 2017

Abstract
Background: Restricted diffusion within the splenium of the corpus callosum has been described by other authors in various conditions, however, restricted diffusion in the entire corpus callosum or isolated involvement of the splenium, genu, or body has been infrequently reported on magnetic resonance imaging (MRI) in neonatal hypoxic–ischemic encephalopathy. We report a series of cases showing different patterns of involvement. Methods and Materials: Perinatal imaging with MRI including diffusion-weighted imaging was performed in 40 neonates with hypoxic–ischemic encephalopathy, including 11 premature neonates. Sixteen out of 40 patients demonstrated restricted diffusion within the corpus callosum. Out of 16 patients, 9 showed restricted diffusion in the entire corpus callosum, 4 had isolated splenium involvement, 2 had body and splenium signal abnormality, and 1 showed diffusion restriction only in the genu. Conclusions: Changes in the corpus callosum were also associated with more severe clinical presentation of encephalopathy. Restricted diffusion within the corpus callosum in infants with hypoxic–ischemic encephalopathy is often associated with extensive brain injury and appears to be an early neuroradiologic marker of adverse neurologic outcome.

Published: January 2017

Introduction:
The increasing use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology to examine pancreatic neoplasms has led to an increase in the diagnosis of metastases to the pancreas. Renal cell carcinoma (RCC) is the most common metastasis to the pancreas. Our study examines 33 cases of metastatic RCC to the pancreas sampled by EUS-FNA from four large tertiary care hospitals.

Materials and Methods:
We searched the cytopathology database for RCC metastatic to the pancreas diagnosed by EUS-FNA from January 2005 to January 2015. Patient age, history of RCC, nephrectomy history, follow-up postnephrectomy, radiological impression, and EUS-FNA cytologic diagnosis were reviewed.

Results:
Thirty-three patients were identified. The average age was 67.5 years (range, 49–84 years). Thirty-two patients had a previous documented history of RCC. One patient had the diagnosis of pancreatic metastasis at the same time of the kidney biopsy. Thirty-one patients had been treated with nephrectomy. Twenty-seven patients were being monitored annually by computed tomography or magnetic resonance imaging. Twenty-five patients had multiple masses by imaging, but 8 patients had a single mass in the pancreas at the time of EUS-FNA. EUS-FNA of 20 cases showed classic morphology of RCC. Thirteen cases had either “atypical” clinical-radiologic features or morphologic overlaps with primary pancreatic neoplasms or other neoplasms. Cell blocks were made on all 13 cases and immunochemical stains confirmed the diagnosis.

Conclusions:
EUS-FNA cytology is useful for the diagnosis of metastatic RCC to the pancreas. Cytomorphology can be aided with patient history, imaging analyses, cell blocks, and immunochemical stains.

Published: January 2017

Background:
SurePath® is an ethanol-based liquid fixative. In addition to ethanol, it also contains a small amount of formaldehyde (<0.2%). The aim of this study was to investigate the immunoreactivity of cells stored for different lengths of time in the SurePath liquid.

Materials and Methods:
Rest material from one malignant and three benign effusions were fixed in SurePath for 1–12 days. Cytospins were incubated with cytokeratin 7 antibody (AB) to evaluate the staining intensity of carcinoma cells and benign, reactive mesothelial cells. Protocols varied as to pretreatment and AB incubation time.

Results:
Reduced immunostaining intensity was seen within 5 days of storage in the SurePath liquid. It was restored when the pretreatment time was prolonged.

Conclusions:
The small amount of formaldehyde in the SurePath liquid seems to affect the immunoreactivity. Local immunocytochemistry protocols in the cytology laboratories should consider this when optimizing their procedures. Postfixation with formalin should be omitted.

Inter-temporal R&D and Capital Investment Portfolios for the Electricity Industry’s Low Carbon Future
Authors: Santen Nidhi R. , Webster Mort D. , Popp David , Pérez-Arriaga Ignacio 
Published: January 2017

ABSTRACT A pressing question facing policy makers today in developing a long-term strategy to manage carbon emissions from the electric power sector is how to appropriately balance investment in R&D for driving innovation in emerging low- and zerocarbon technologies with investment in commercially available technologies for meeting existing energy needs. Likewise, policy makers need to determine how to allocate limited funding across multiple technologies. Unfortunately, existing modeling tools to study these questions lack a realistic representation of electric power system operations, the innovation process, or both. In this paper, we present a new modeling framework for long-term R&D and electricity generation capacity planning that combines an economic representation of endogenous non-linear technical change with a detailed representation of the power system. The model captures the complementary nature of technologies in the power sector; physical integration constraints of the system; and the opportunity to build new knowledge capital as a non-linear function of R&D and accumulated knowledge, reflective of the diminishing marginal returns to research inherent in the energy innovation process. Through a series of numerical experiments and sensitivity analyses— with and without carbon policy—we show how using frameworks that do not incorporate these features can over- or under-estimate the value of different emerging technologies, and potentially misrepresent the cost-effectiveness of R&D opportunities.
Escala de mitos en duelo. Relación con el estilo de afrontamiento evitativo y validación psicométrica
Authors: Bermejo Jose Carlos , Villacieros Marta , Fernandez-Quijano Invencion 
Published: January 2017

ResumenEn la elaboración del duelo, tanto las estrategias particulares de afrontamiento como el concepto que maneja el doliente sobre la muerte son fundamentales. El propósito de esta investigación es analizar la relación entre el estilo de afrontamiento evitativo y los mitos o creencias erróneas sobre el duelo además de establecer la dimensionalidad de la Escala de Mitos en Duelo (EMD; Amurrio y Limonero, 2007). Dicha escala se pasó a una muestra de 265 personas (81 % mujeres y 19 % hombres). Los indicadores revelaron buen ajuste a los datos, estableciéndose dos dimensiones: el primer factor recoge la creencia de que es mejor no recordar lo sucedido y el segundo que es mejor no expresarlo. Los resultados señalaron que el uso de estrategias de afrontamiento evitativo, ser hombre, la ausencia de formación universitaria y el haber perdido a un familiar de segundo grado, predicen un mayor nivel de mitos en duelo. AbstractIn the elaboration of the duel both individual coping strategies as the concept that manages the grieving over death are fundamental. The purpose of this research is to analyze the relationship between the avoidant coping style and myths or misconceptions about the duel, apart from establishing the dimensionality of the Scale of Myths in Duel (SMD) (Amurrio and Limonero, 2007). The scale was passed to a sample of 265 people (81 % of women and 19 % men). Indicators revealed good fit to the data settling two dimensions: the first factor reflects the belief that it is better not to remember what happened and the second that it is better not to express it. Findings pointed that the use of avoidant coping strategies, being a man, the absence of university training and having lost a second-degree level of closeness familiar, predict a higher level of myths in duel.
Sobre la desensibilización sistemática. Una técnica superada o renombrada
Authors: Vallejo-Slocker Laura , Vallejo Miguel A. 
Published: January 2017

ResumenEn este trabajo se lleva a cabo una reflexión sobre la pionera Desensibilización Sistemática (DS), cuyos principios parecen haber sido asumidos por otros procedimientos de mayor popularidad. Aunque olvidada, los fundamentos de la DS cuentan con referencias a nuevos enfoques como la Teoría de Marcos Relacionales (RFT) o el mindfulness, así como una gran variedad de aplicaciones más allá del abordaje de las fobias específicas. Desde un punto de vista teórico y en comparación con otras técnicas de exposición, la DS contribuye de mejor manera a la reducción de la ansiedad mediante: la relajación, la presentación gradual y el aprendizaje duradero de una respuesta alternativa bajo un contexto estimular variado que favorece la generalización. Además la DS es mejor recibida por los pacientes, es un procedimiento flexible y con unas bases teóricas consolidadas, siendo estas razones suficientes para revalorar la técnica. AbstractThis paper constitutes a reflection about the pioneer Systematic Desensitization (SD), which bases seem to have been assumed by more popular procedures. Al­though SD fell into oblivion; its foundations remain as part of new approaches such as the Relational Frame Theory or mindfulness and targets a wide range of disor­ders besides specific phobias. Theoretically speaking and in comparison, with other exposition techniques, SD contributes in a better way to the reduction of anxiety by: relaxation, calibration of the exposures and a long-lasting learning of an alternative response within a varied sti­mulating context that favors generalization process. Mo­reover, SD is better accepted by patients and is a flexible procedure with consolidated bases. These serve as suffi­cient arguments to revalue this technique.
Perfeccionismo infantil: Normalización de una escala argentina para su evaluación
Authors: Oros Laura , Vargas-Rubilar Jael 
Published: January 2017

ResumenLa Escala de Perfeccionismo Infantil (Oros, 2003), es un instrumento argentino de sencilla aplicación que permite indagar la presencia de pensamientos irracionales en forma de autodemandas y las consecuentes reacciones perfeccionistas ante el fracaso de las mismas. La escala ha demostrado tener un buen funcionamiento psicométrico al ser aplicada en muestras de niños escolarizados de entre 8 y 13 años de edad, sin embargo, no existen hasta el momento baremos nacionales que arrojen valores de referencia para la interpretación de los puntajes. El objetivo del presente trabajo es ofrecer los resultados de la normalización de dicha escala, estableciendo diferencias por género y edad. Dos mil doscientos setenta niños y niñas completaron la escala en el contexto escolar. Análisis de variancia (ANOVA y MANOVA) indicaron puntuaciones más elevadas en los varones en la escala global y en la dimensión de autodemandas. Respecto a la edad, se encontraron diferencias en la dimensión de autodemandas, presentando más autoexigencias irracionales los niños menores (8 a 10 años). Por lo tanto, se presentan los valores normativos segregados por género y edad, los cuales constituyen un aporte significativo para la investigación y la práctica clínica. AbstractChildren’s Perfectionism Scale (Oros, 2003) is an ar­gentinian instrument of simple implementation which allows investigating the presence of irrational thought, showed as a self-demanding behavior, and its related perfectionist reactions when those self-demands are not fulfilled as expected. The scale has proved to be a good psychometric instrument when applied in a sample of children attending school between the ages of 8 and 13 years old. However, it has not been de­veloped so far any national scale that provides refer­ence values for the interpretation of the scores. The aim of this paper is to provide the results of such scale standardization, establishing differences based of gender and age. Two thousand two hundred and seventy children completed the scale within the school context. Analysis of variance ANOVA and MANOVA showed higher scores for the boys in the global scale and in the self-demand dimension. With regards to age, it has been found that children aged 8 to 10 show differences in the self-demand dimension showing more irrational self-demands. Therefore, normative values are presented and segregated by gender and age, which represents a significant contri­bution for clinical practice and research.
El primer principio, `Potencia de todas las cosas’, En Plotino
Authors: Zamora Calvo José María 
Published: January 2017

Plotino denomina al Uno-Bien potencia de todas las cosas (δύναμις πάντων), o potencia total (δύναμις πᾶσα). Asimismo, el primer principio es designado como más allá del ser, anterior o superior a todas las cosas, pero nunca dice que sea anterior o superior a la potencia. El Uno no es ninguna de todas las cosas (οὐδὲν τῶν πάντων), es decir, es “diferente de todas las cosas”, porque es “anterior a todas ellas” y está “más allá de todas las cosas”, porque es “principio de todas las cosas”, “causa de todas las cosas” o también “potencia de todas las cosas”, pero potencia activa y productiva de todo, y no pasiva o receptiva de todo como la materia.
Utilization and Equivalence of the Department of Trade and Industry (DTI) Personal Computers for Public Schools Project: An IPO Model
Authors: BAHIAN LITO P. 
Published: January 2017

The use of technology to address educational reforms has contributed largely to increasing the academic performance. The study was conducted to determine the utilization and equivalence of the DTI PCPS project Batch 4to the academic performance of the recipient schools of Zamboanga del Sur. It employed the descriptive design. A validated research survey questionnaire was used. Descriptive statistics such as frequency count, percentages, and weighted mean were used. The results revealed that both teachers and students “rarely” used Microsoft Office applications, educational games, and Internet applications. In terms of ICT knowledge level, both teachers and students manifested “advanced” in the PC basics, MS Word, and Internet applications and “intermediate” in MS Excel and MS PowerPoint. The academic performance of the recipient schools, as manifested in the MPS, revealed that there was an increase within the three school years of implementation (2010-2013). The study concludes that utilization of the computers granted from the DTI PCPS Batch 4 project facilitates learning positively. The computers granted were inadequate, and computer education was integrated with the curriculum. Hence, the study theorizes that academic performance of students at the secondary levels can be optimized by integrating ICT into the curriculum.

Published: January 2017

The quest for better strategies in teaching is a never-ending process. This scenario is heightened more by the myriad online instructional materials fit for classroom use. The study aimed to determine the effectiveness of video lecture materials for statistics proficiency of first year students of Davao Doctors College.The researchers employed quasi-experimental design that involved purposively chosen 31 students for the control group and 26 students for the experimental group. The control group received traditional instruction while the experimental group utilized video lecture materials as the instructional tool. The questionnaire consisted 50 multiple choice items and established a reliability index of .82. This investigation used t-test analysis to establish the same level of statistics proficiency among the students before the conduct of the study. The study concluded that both learning strategies were effective in teaching students the basic concepts of statistics as indicated by the significant improvement of their pre-test to posttest scores. Although the posttest results of the students who were taught using video lecture materials were higher than those supervised using lecture method, the significance of this difference was never established. Thus, the use of video learning material as an instructional tool in statistics is equally effective with the traditional lecture method.
