Centros comerciales, globalización y patrones de consumo: factores de transformación urbana en Bogotá (2006-2012)
Authors: Moreno-Cruz Carolina , Osorio-Cáceres Samuel Fernando
Published: March 2024

Este artículo analiza la relación entre globalización, centros comerciales y patrones urbanos de consumo, a partir del abordaje de cuatro proyectos en la ciudad de Bogotá construidos entre el 2006 y el 2012: Tintal Plaza, Titán Plaza, Santafé y Hayuelos. Así, en este documento se examinan algunas teorías sobre la globalización y su relación con los espacios urbanos que se destinan a la construcción de grandes centros comerciales. Luego, se analiza la evolución y el impacto de dichos lugares en su entorno, al igual que los elementos en común de los cuatro casos respecto a los patrones urbanos de consumo. Por último, se explica la categoría de patrón urbano de consumo y se desglosa en diferentes dimensiones: patrón urbano de movilidad complementaria, patrón residencial, patrón de procesos de inversión y patrón de comercio derivado.
El decir y el deseo: silencio y violencia del significante
Authors: Cardozo-González Santiago
Published: March 2024

La extensa reflexión sobre el enunciado y la enunciación (respectivamente, producto material e instancia histórica que lo produce) debería tener siempre en cuenta una teoría del sujeto que habla, que, para el caso que voy a plantear aquí, implica también una teoría del deseo, del inconsciente y del silencio. En otras palabras, una teoría de la significación que procure dar cuenta de la relación entre la enunciación y el enunciado debe integrar aquello que no es aprehensible por las diferentes disciplinas lingüísticas, cuyo efecto más sobresaliente (en un sentido también geográfico) es el equívoco. De acuerdo con lo señalado, en primer lugar, se plantearán la relación entre la enunciación y el deseo y, sobre todo, el modo en que este aparece en la lógica misma de funcionamiento del sistema lingüístico. En segundo, se mostrará la articulación entre el deseo y el silencio (lo real), articulación inherente a la enunciación como instancia de apropiación de la palabra y de su puesta en juego. Por último, se extraerán algunas de las principales consecuencias de las relaciones o articulaciones discutidas.
Ecos literarios en The metal opera I y II de Avantasia
Authors: Duarte-López Andrés Felipe
Published: March 2024

El objetivo de este artículo es el reconocimiento de los ecos literarios presentes en los álbumes The metal opera II y II de la banda alemana Avantasia con el fin de relacionarlos con la idea de una música vinculada a la literatura desde una postura funcional, y no instrumental, generada a partir de la utilización de recursos narrativos además de tópicos literarios que estructuran la historia y constituyen el planteamiento de una crítica liberal a los principios morales y religiosos que regían en los tiempos renacentistas. Este análisis se llevará a cabo a partir de la evolución histórica del género musical que justifica el planteamiento musical del autor, asimismo se trabajarán las nociones de álbum conceptual, ópera y ópera rock para determinar las relaciones con la literatura basadas en elementos medievales, religiosos, musicales y literarios. Finalmente, se buscará contribuir con una hipótesis sobre una nueva manera de relacionar la literatura con la música más allá del cambio de formato, visto como una constante en la historia, y que se podría considerar como una nueva manera de contar historias.
Three Decolonial Research Methodologies: Interrogating Qualitative Research in English Language Teaching Education
Authors: Castañeda-Londoño Adriana , Samacá-Bohórquez Yolanda , Posada-Ortiz Julia
Published: March 2024

Along this reflection paper, we confront our former understandings of research as women teachers-researchers who intend to take the Epistemologies of the South as ways of being feeling-thinking-doing English language teacher education and research. A personal, academic, and collective journey has intersected and driven us into the decolonial turn to research ELT. Moreover, in this paper, we will share our uncertainties and struggles in an overt attempt to question our personal fine-grained colonial paradigms to find possible ways to demonumentalize research. Our research methodologies are intended to overcome a Western rationality of knowledge production that ingrains the ways through which our knowledge, research, and pedagogical practices are to be constructed. Walking the paths of decoloniality, we have moved from universal to more pluriversal understandings; we have constructed, co-constructed, valued and rescued situated knowledges emerging from our experience in our Global South. In the process, we have lived a mobilization of visions and pathways that destabilize and relocate our practices with a deep relation to that sense of locality that is ours. The aim of the following paper is to socialize how, through our research projects, we have envisioned inter-epistemic relational methodologies, hybrid, and testimonial narratives to portray ways to research English language teacher education with a decolonial spirit.
English-Medium Instruction for the Internationalization of the Curriculum: Teachers’ Motives and Expectations
Authors: González-Bello Edgar Oswaldo , García-Meza Isabel María , Estévez Nenninger Etty Haydée
Published: March 2024

This research article presents the results of a research that aimed to analyze the motives and expectations of teachers from a public university in northwestern Mexico when participating in the internationalization of the curriculum through Englishmedium instruction (EMI). The analysis is based on the variables such as discipline, seniority, type of contract and frequency of teaching in English. A mixed methodology was employed to analyze quantitative and qualitative data, collected through a digital instrument addressed to a total of 42 teachers who were accredited to teach subjects in English, and 36 complete questionnaires were answered. The results allow us to conclude that most professors from all disciplines agree that their main reason for participating in internationalization through EMI is “to support institutional initiatives”; in contrast, “receiving economic incentives from institutional programs” was a reason for participation with marked differences according to discipline and type of contract. The qualitative analysis concludes the existence of positive conceptions around this type of education, as it is favorable for the university and a possible source of economic remuneration. Although teachers express an intrinsic motivation towards training and teaching in English, the lack of equal economic incentives could be a cause of limited teacher participation.

A partir de esta revisión, se establecen algunas tendencias, como la persistente dicotomía entre el paso de la aritmética al álgebra, la zona de emergencia del álgebra y los conocimientos pedagógicos de los profesores de matemáticas. Además, se identifican ciertos desafíos, como la necesidad de llevar a cabo investigaciones orientadas al fortalecimiento de procesos en los estudiantes, como la comunicación, el razonamiento y la argumentación.
Caracterizar la innovación para validar la práctica educativa
Authors: Rosselló María Rosa , Pinya Carme , Morcillo Virginia
Published: March 2024

Este artículo persigue identificar los principales indicadores que definen, a nivel teórico, cualquier innovación educativa. El trabajo se enmarca en el debate actual sobre cómo replantear la escuela en el siglo xxi, ante la creciente proliferación de experiencias innovadoras que, impulsadas por administraciones educativas o por equipos docentes, se desarrollan sin sistematizar evidencias de los resultados obtenidos. Teórica y metodológicamente, el estudio adopta el enfoque propio de la metainvestigación. Desde el punto de vista metodológico, se lleva a cabo una revisión sistematizada de la bibliografía, analizando la producción científica de los diez últimos años. Se procedió a un análisis de contenido, lo que permitió establecer un decálogo de términos. En la segunda fase, se sometió este decálogo a la validación de jueces, quienes validaron los indicadores de innovación en función de tres categorías (Congruencia, Pertinencia y Claridad) analizadas a partir de porcentajes de acuerdo y el valor free-marginal kappa. Los resultados del estudio apuntan a que la concordancia media entre los jueces varía, pues es buena para cuatro de los indicadores propuestos, media en otros cinco y débil, en solo uno de los casos. La revisión sistematizada y validada ofrece un panel de diez indicadores como rasgos básicos que caracterizan una innovación educativa: Novedad, Intencionalidad, Contextualización, Aprendizaje significativo, Planificación y documentación, Evaluación, Valor añadido, Sostenibilidad, Comunicación y colaboración y Liderazgo pedagógico. Este decálogo supone un primer paso en la confección de una hoja de ruta capaz de guiar la recogida de evidencias y la validación de las experiencias.

Authors: González-Gijón Gracia , Alemany-Arrebola Inmaculada , Ruiz-Garzón Francisca , Ortiz-Gómez María del Mar
Published: March 2024

El proceso de construcción de género es un proceso intra- e interindividual que se desarrolla por una interacción constante del sujeto con su contexto social y cultural, en el que se adquieren creencias y actitudes sobre lo que es típico de hombres y mujeres. El presente estudio, desarrollado en Melilla, ciudad española multicultural situada al norte de África, analiza los estereotipos de género basados en esas creencias culturales de adolescentes, teniendo en cuenta el sexo y su procedencia cultural. Para esto, se ha seleccionado una muestra de 1837 estudiantes de 1.º y 3.º de Educación Secundaria Obligatoria (eso) y 1.º de bachillerato, a los que se les solicitó contestar un cuestionario elaborado ad hoc para esta investigación. Los resultados, después de la aplicación de la prueba t y el análisis multivariado de covarianza, indican que los chicos tienen más arraigados los estereotipos de género que las chicas, y en ambos casos es elevada su interiorización. Además, la procedencia cultural influye en la consolidación de estas creencias de género como consecuencia de los estilos de crianza y valores culturales en los que se han socializado.
Multipli interventi di ICD in un paziente affetto da cardiomiopatia dilatata con recupero della frazione di eiezione
Authors: Biasin Marco , Berton Giampaolo
Published: March 2024

Questo caso clinico illustra le sfide complesse legate alla gestione di un uomo di 60 anni con defibrillatore cardiaco impiantabile (ICD) per cardiomiopatia dilatativa. Nonostante la normalizzazione della frazione di eiezione nel 2015, il paziente ha subito 147 scosse asintomatiche per svariate tachicardie ventricolari ad alta frequenza che hanno infine portato all’esaurimento della batteria del dispositivo e all’ospedalizzazione del paziente. Nonostante livelli normali di troponina, le persistenti tachiaritmie ventricolari asintomatiche hanno richiesto un intervento farmacologico comprensivo di beta-bloccanti e mexiletina ed un approccio invasivo con l’ablazione trans-catetere della tachicardia. Questo caso mette in discussione le concezioni prevalenti sul danno miocardico legaato agli shock da ICD. Tuttavia, dato il potenziale danno miocardico indotto dagli shock e alla loro associazione con eventi avversi, risulta necessaria una gestione individualizzata in termini di terapia antiaritmica e di programmazione dell’ICD.
Potential controlled electrochemical coating and characterization of nanocrystalline Sn-Zn based thin films
Authors: ÜNVEROĞLU ABDİOĞLU Begüm
Published: March 2024

Sn-Zn thin films are commonly used in many areas of the industry, and the facile production of these layers is vital. This study aims to produce Sn-Zn layers via potentially controlled electrochemically deposited coatings. The potentially controlled mode was used to eliminate the extensive hydrogen evolution reaction during the electrochemical processes. The electrochemical reduction and oxidation reactions were first investigated with cyclic voltammetry to determine the applied potential sets. Later, cathodic pulse potential electrodeposition of the layers was performed. The characterization of the coated Sn-Zn thin films was performed with an X-ray diffraction device (XRD), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), four-point probe, potentiodynamic polarization measurements, and electrochemical impedance spectrometry. As the cathodic pulse potential value increased, the ratio of Zn in the Sn-Zn alloy increased, and the microstructure of the layers was also affected. Electrochemical studies showed that the corrosion resistance of the Sn-Zn thin films increased with the increasing Zn amount in the coating.

Investigation of the molecular effects of isatin on HepG2 and AML12 cell lines
Authors: ŞUMNULU Deniz
Published: March 2024

Isatin is an indole-derived organic compound. It is a natural component of the Couroupita guianensis plant. It is also the metabolic derivative of the human body hormone adrenaline. Studies have shown the anti-tumoral effects of isatin derivatives. In this study, the cytotoxic effects of isatin on HepG2, a hepatocellular cancer cell line was investigated. Additionally, its cytotoxic and protective-proliferative effects on AML12, a healthy liver cell line was investigated. This evaluation was conducted using MTT, fluorescent staining, wound healing, and real-time polymerase chain reaction analyses. The IC50 values for 48 hours of isatin application were calculated as 186.23 µM for HepG2 and 7.05 mM for AML12. The analysis of wound healing and fluorescent staining at varying doses of HepG2 application revealed suppression of proliferation and triggered apoptosis in HepG2 cells. In contrast, AML12 cells exhibited promoted proliferation under similar conditions. Moreover, the observed upregulation of oxidative stress genes CuZn/Mn-SOD and mitochondrial apoptotic pathway genes Bax, cleaveled-Cas3, APAF1, and p53 in HepG2 cells contrasted with their decreased expression in AML12 cell lines. These results suggest the potential of natural isatin as a promising anti-cancer agent for liver cancer cell lines and as a protective supplement for healthy liver cells.

Authors: Kopylov Andrey E. , Neudakhin Mikhail A. , Popova Natalya V.
Published: March 2024

BACKGROUND: The development of visual deficit due to glaucoma or cataracts significantly limits motor activity and reduces the independence of elderly patients from others in daily activities. However, resilience among older patients with primary open-angle glaucoma and cortical cataract remains largely unexplored.
AIM: To analysis of the resilience of elderly patients with primary open-angle glaucoma and cortical cataract
MATERIALS AND METHODS: For this study, two clinical groups were formed: patients aged 60–74 years with primary open-angle glaucoma without secondary cataracts in the amount of 135 people (64 men and 71 women) and patients with cortical cataracts without combination with glaucoma in the number of 128 people (59 men and 69 women). To study the viability of patients, the Connor-Davidson Resilience Scale-25, validated in the Russian Federation, was used.
RESULTS: To the greatest extent, representatives of both study groups differed in the subdomain “security in relationships” and “positivity of accepted changes” with a representative difference. The compared groups of patients also had statistically significant differences in such an important subdomain as individual perseverance (p 0.05) and competence in mean scores for each cohort. At the same time, there was a deterioration in age-related vitality according to the final parameter of patients on the Connor-Davidson Resilience Scale-25. At the same time, the decrease in the average value of the integral parameter according to the age-related vitality scale used in the study was 16.3 points with a statistically significant difference (p 0.05) in the group with cortical cataracts.
CONCLUSION: As a result of the study, it was found that cortical cataracts and primary open-angle glaucoma contributed to a decrease in the vitality of elderly patients, and this was more pronounced in patients with primary open-angle glaucoma, which should be taken into account when justifying medical and psychological support for such patients.

Authors: Yahya Nadiyah Kholilah , Nursita Rizki Dian , Kohar Halilintar Yusuf
Published: March 2024

The enactment of Law No. 23 of 2014 concerning Local Government in Indonesia has paved the way for increased international engagement by local authorities, a practice known as paradiplomacy. In this context, Nusa Tenggara Barat (NTB) has sought to expand its international cooperation, notably with Bukhara Province, focusing on developing the halal tourism sector. This study critically examines the process and challenges of institutionalizing paradiplomacy between NTB and Bukhara, with a particular focus on halal tourism development. However, the institutionalization of this international cooperation has encountered significant obstacles. Utilizing a qualitative research approach, this investigation analyzed a variety of primary and secondary sources to uncover the underlying factors impeding the process. The study identified several key barriers to the institutionalization of NTB-Bukhara paradiplomacy, including shifts in leadership and policy priorities within NTB's government, delays in formalizing cooperation agreements, a lack of expertise in international relations among local government officials, restrictive central government regulations, and cultural and conceptual discrepancies in the understanding of halal tourism between the two regions. Addressing these challenges requires a multifaceted approach, involving not only policy reform and capacity building at the local government level but also a deeper cultural and conceptual alignment between cooperating entities.
Indian women should be encouraged to use combined contraceptive vaginal ring
Authors: Das Sourav , Sinha Tiasa
Published: March 2024

This article is to spread awareness among Indian women regarding vaginal contraceptive ring use. Since the introduction of hormonal contraceptives, combined oral pills (COCs) have become the method of choice for many women. Although COCs have improved significantly, they have got some disadvantages. This has prompted development of non-oral hormonal contraceptive methods. One of them is combined contraceptive vaginal ring (CCVR). Most studies found out that CCVR was associated with good cycle control and was not associated with vaginal or cervical abnormalities. Treatment related adverse effects like headache, leucorrhoea, nausea, etc and systemic side effects are minimal. Most women found the ring easy to insert, easy to remove and were satisfied with ring usage. So it can be concluded that CCVR is an effective contraceptive with good cycle control that is well tolerated. It is associated with high user and partner acceptability and minimal local and systemic effects. Therefore gynaecologists and policy makers should give more emphasis on its routine use.

Published: March 2024

Foreign body (FB) ingestion in adult and children population is not uncommon but accidental. Same is rare in neonates and infants. Many of FB ingestion go unnoticed or unexpressed if baby is preverbal. Most of the foreign bodies pass spontaneously per anal. Only the larger size or sharp FBs get stuck in places of gastro intestinal tract and presented on emergency Department. Similarly corrosive and toxic FB also invites immediate attention. Literature on the clinical aspects of the foreign body ingestion among neonates and infants was searched electronically through PubMed and individual study. Relevant articles were reviewed thoroughly and summarized. Instances of foreign body ingestion (FBI) in neonate and adult are in ascending trend over last several years. Imaging and identification of radiolucent FBs become challenging for surgeons. Conservative treatment for spontaneous evacuation, endoscopic retrieval and surgical removal are the modalities for FBI management. Two relevant rare reports are appended as the case study. Where the reported FBs are gold fingering and sharp open safety pin in infants. One was managed conservatively for per anal evacuation and other needed endoscopic retrieval with general anesthesia.

Abnormal hormonal balance and cellular interactions mediated growth factors leading to ductal and cellular hyperplasia is the main pathophysiological cause of the disease.

This prospective observational study was conducted on 100 SGT medical college and hospital patients from January 2021 to august 2022 to assess the detailed clinicopathological study of patients with fibrocystic disease breast diagnosed clinically with relevant investigations.

In our study, we found that fibroadenoma is the maximum among all Fibrocystic breast diseases, i.e. 34%, with the majority between 11-30 years. It rises in the 2 decade of life and peaks in the 4 decade. Non-cyclic mastalgia constituted 29% of the total cases, with most patients lying in the age group of 31-50 years, where mastalgia was the presenting complaint in most cases. Inflammatory breast diseases formed 4% of the total, with the main presenting symptoms being mastalgia, fever and nipple discharge. Again, it mainly included patients from the age group of 31-50 years. Gynaecomastia and breast abscess were diagnosed in 3 cases, with all lumping on the right side of the breast.

Our study attempted to derivate the spectrum of breast diseases in different age groups among patients reporting to SGT medical college and hospital, SGT University, Gurugram, Haryana. Apart from the incidence of various fibrocystic diseases, various other facts were recorded. Benign breast lesions were recorded to comprise the bulk of the patients presenting with breast disorders and were maximum in the reproductive age group. Breast sclerosing adenosis should be identified by excluding the malignancy. Most Fibrocystic breast diseases have been managed conservatively.

Those patients whose inflammatory markers (CRP, S LDH, D DIMER) are not decreasing after 48 hours of corticosteroids therapy may be given Tab Tofacitinib 10mg bid for a period of 14 days or till the decrease in inflammatory markers, whichever is earlier. Oxygen requirement and inflammatory markers were assessed every 3 day.

Out of 27 patients who didn’t respond for corticosteroids 20 were given the drug tab tofacitinb 10mg BD. CRP in the both the steroid non responders and steroid responders groups was high till day 9, on day 14 the CRP levels were normal in 50% of steroid non responders. S LDH levels in the steroid non responders group was in the decreasing trend i.e., on day 14 it was normal in 70% of patients.. The levels of D DIMER in tofacitinib group was high till day 6, and on day 14 the D-DIMER levels were normal in 40% patients. Oxygen requirement showed drastic changes in the steroid non responders group.

Among patients hospitalized with COVID-19 pneumonia, addition of Tofacitinib to steroid non responders group showed early improvement in their clinical and biochemical levels. Hence, Tab tofacitinib can be recommended an adjunct to steroids for early clinical and biochemical improvement for treatment of moderate to severe cases of COVID-19.

There is a high psychological morbidity that is reported in undergraduate medical students. This can range from stress, anxiety, interpersonal problems, suicide to psychiatric disorders. The objective of our study was to assess the prevalence of depression, anxiety and stress amongst the first year undergraduate students in a medical college.

A cross sectional study was undertaken after approval from institutional ethical committee which included the 150 undergraduate medical students of 1 year. A semi structured performa which included socio demographic profile was used along with Depression, Anxiety and Stress Scale (DASS 42) for assessment.

Most of the participated students were females (57.5%). All of the students (100%) were residing in hostel and were unmarried. Stress was reported by majority (86.7%) of the students with few reporting low social support (7.3%). Single responses to causes of stress were in majority (74.6%). Prevalence of depression, anxiety and stress was 56%, 68.7% and 61.3% respectively.

A considerable number of undergraduate medical students are affected and suffer from anxiety, stress and depression. There is an urgent need to address the issue and give more attention towards mental health of students.

Serum lactate levels rise during Cardio-Pulmonary Bypass (CPB) surgery for a variety of reasons, including peripheral circulatory failure, haemodilution, or excessive use of inotropic agents. Additionally, it has been reported that elevated serum lactate levels during the perioperative period are strongly associated with the worst postoperative outcomes, including mortality.

To find out the beneficial effects of an oxygen blender during cardiopulmonary bypass in reducing lactate levels in patients undergoing open-heart surgery.

This Prospective comparative study was done on 150 patients who underwent open-heart surgeries. Patients were divided into group A-75 patients: with direct oxygen flow without oxygen blender, group B- 75 patients: with oxygen blender. The serum lactate levels during CPB, postoperative levels and outcomes were monitored and both the groups were compared.

Average FIO2 of 38 % was enough to maintain PO2 of 168 mm Hg by using the oxygen blender with the flow rates. Group A showed severe hyperoxemia (p-value <0.0001) and hypocarbia, resulting in severe respiratory alkalosis during CPB and severe acidosis in the immediate postoperative period in most of the cases. Group B showed a significant reduction in the serum lactate value at CPB one hour with 3.1 mmol/l reductions, 3.8 mmol/L reductions at 2 hours and 4.4 mmol/L reductions at ICU arrival (p-value <0.0001).

Serum lactate values reduced significantly in the patients with oxygen blender. Study proved that application of an oxygen blender during CPB improved the postoperative results following open-heart surgeries. The researchers conclude that using an oxygen mask was beneficial.

To assess how COVID-19 pneumonia differs from other pneumonias in terms of the chest computed tomography features.

In this study we included 170 clinically diagnosed cases pneumonia referred to department of radio diagnosis subjected to HRCT thorax which include out patients and in patients out of which 127 patients tested RT-PCR positive for Covid 19 pneumonia for a total duration of 1 year. (March 2020 to March 2021). The parenchymal abnormalities including Ground glass opacities (GGO), ground glass opacities with interlobular septal thickening (crazy paving), GGO with consolidation, consolidation, pulmonary nodules, tree in bud appearances, bronchiolar wall thickening, interlobular septal thickening , halo sign, reverse halo sign, cavitation and pleural effusion and were observed and categorized along with determination of pattern of distribution on chest CT.

127 patients who tested positive for COVID 19 and 43 patients with other pneumonia (such as community-acquired pneumonia) were visited, and CT scans were analysed to determine the presence and distribution of the disease pattern.

Patients with COVID 19 pneumonia primarily have peripheral-based lesions (90%), whereas patients with other pneumonias primarily have mixed patterns (70%)—a difference that is statistically different (p 0.05).

Statistics show that COVID 19 had higher bilateral involvement than other pneumonia (p<0.05).

In COVID-19 pneumonia, GGOs, GGOs with interlobular septal thickening (crazy paving), and GGOs with consolidation with peripheral and basal predominance in bilateral lung parenchyma are the most common imaging patterns and findings. These findings will help us distinguish COVID-19 pneumonia from other causes of pneumonia. There is less evidence of tree in bud, pure consolidation, cavitation, and bronchiolar wall thickening.

Thyroid nodules are a frequent occurrence. With the widespread use of sensitive imaging methods, a growing number of thyroid nodules are being discovered by chance. High resolution ultrasonography (HRUSG) has emerged as the most appropriate imaging modality for the assessment of thyroid nodules.

To Evaluate thyroid nodules by of high resolution ultrasonography (HRUSG) and its correlation with Fine needle aspiration cytology (FNAC).

Prospective study done in the department of radiology at Maheshwara medical college and Hospital, Chitkul, near Isnapur, Patancheru, Sangareddy, Telangana for duration of 3 years. A total of 80 cases were studied.HRUSG was done in all cases and Fine Needle Aspiration cytology was done. Radiological and pathological correlation was done and Sensitivity, specificify PPV, NPV and accuracy were calculated.

Females were predominant (62.5%) when compared to males (37.5%). Among 80 thyroid nodules , colloid nodule noted in 42.5% cases, Nodular goitre in 27.5%, Hashimotos thyroiditis and follicular adenoma in 12.5%cases and Malignancy in 5% cases

HRUSG is a sensitive and specific imaging technique that has a high level of accuracy in the evaluation of thyroid nodules. Solid composition, hypoechogenicity, taller-than-wider form, ill-defined edges, and the presence of calcification are the most effective sonographic markers for predicting cancer.

The objectives of this study were to detect the rotator cuff injury using high-resolution ultrasonography in clinically suspected patients, compute MRI findings and compare the effectiveness of ultrasound and MRI diagnostically in such patients.

30 patients who were suspected to be suffering from rotator cuff injury were referred to the Department of Radiodiagnosis, Medical Trust Hospital, Kochi, Kerala. MRI and high-resolution ultrasonography were used to evaluate them after taking their written consent. The present study was carried out from November 2018 to October 2019.

In partial thickness tears, the specificity of ultrasound was 87.5% and sensitivity was 72% whereas it was 83.3 % and 95.8% respectively for full-thickness tears. MRI was more sensitive than USG in evaluating the capsular and labral pathologies. MRI was the most sensitive and specific modality in the evaluation of shoulder pain. A specificity of 94% and a sensitivity of 92.3% was seen in relation to MRI in case of partial thickness tears; whereas in full thickness tears a specificity of 95.8% and a sensitivity of 100.0% were seen. In calcific tendinitis, picking bursal fluid and impingement, MRI was better than USG and also highly sensitive for labral tears.

In the evaluation of shoulder pain, MRI is the most appropriate evaluation modality and in case of labral tears it is highly sensitive. When compared to USG, MRI is better in picking bursal fluid, impingement as well as calcific tendinitis and also in evaluating labral and capsular pathologies.
