From a creative worker to a noonomy human
Authors:   S.Y. Witte Institute for New Industrial Development, Khabibullina Z.R.
Published: October 2023

the main provisions of the theory of noonomy and the new industrial society of the second generation (NIS.2) are presented in the paper. It is emphasized that the contours of a new technological space (in the terminology of S.D. Bodrunov – noonomy) will be achievable only in the course of the progressive development of human creative qualities, where the human will simultaneously be personified as the starting point and the end result of global civilizational transformations. A comparison of “noonomy” with the “third industrial revolution” (J. Rifkin) and the “fourth industrial revolution” (K. Schwab) was carried out in the form of a system of steps on the path of theoretical knowledge. It is substantiated that the qualitative changes occurring between the creative worker and the owner of capital in the modern production process can become a transitional stage to the formation of new production in the future, and the intellectual creative function can be a guide to the construction of a qualitatively new model of social development.

School Principals Technological Leadership Self-Efficacies and 21st Century Teacher Skills
Authors: BURAK Döndü , ÖZÜDOĞRU Gül
Published: September 2023

This research aims to explore the technological leadership self-efficacy (TLS) of school principals and their use of 21st-century teacher skills (CTS). Furthermore, the study investigates potential variations in self-efficacy and teacher skills among school principals based on certain variables, including gender, administrative seniority, teaching seniority, education status, participation in in-service training on information technologies, and daily average internet use. The research employs a correlational survey model, a quantitative methodology, to scrutinize the interplay between school principals' TLS and their proficiency in 21st CTS. The study encompasses 102 voluntary school principals employed in public schools during the 2021-2022 academic year as participants. Three data collection instruments are utilized within the study. The data analysis involves descriptive statistics, t-tests for unrelated samples, ANOVA, Pearson correlation analysis, and regression analysis. The research findings indicate that the mean scores for school principals' TLS and their use of 21st CTS are notably high. A moderate, positive, and statistically significant correlation is observed between school principals' technological leadership self-efficacy and their utilization of 21st CTS. Additionally, it is deduced that school principals' 21st CTS significantly predict their TLS. Seminars could be considered to enhance the competencies of school principals in adapting to changing learning-teaching environments driven by technology.

Authors: YAZICIOĞLU COŞGUN Müfide Merve , KAĞAN Mücahit
Published: September 2023

Bu çalışma; üniversite öğrencilerinde görülen riskli davranışların, ahlaki uzaklaşma ve algılanan sosyal destek kavramları ile ilişkisini incelemeyi amaçlamaktadır. Riskli davranışlar, bireylerin hayatlarını olumsuz yönde etkileyen ve onlar için risk içeren davranışlarını açıklayan bir kavram olarak görülmektedir. Riskli davranışlar, özellikle ergenlik ve geç ergenlik dönemindeki bireylerde daha fazla görülen bir durum olarak karşımıza çıkabilmektedir. Bu nedenle bu çalışmada üniversite öğrencileri ile çalışılması uygun görülmüştür.
Çalışmaya katılan grup, 2019-2020 öğretim yılında Erzincan Binali Yıldırım Üniversitesi’ne bağlı beş farklı fakültede öğrenim gören 646 üniversite öğrencisinden oluşmaktadır. Araştırma modeli nicel olup ilişkisel yöntem ile çalışma yürütülmüştür. Riskli davranışların ahlaki uzaklaşma ve algılanan sosyal destek yordayıcı değişkenleri tarafından ne düzeyde yordandığı incelendiğinden ilişkisel çözümleme yöntemlerinden çoklu doğrusal regresyon analizi ve bağımsız örneklemlerde t testi kullanılmıştır.
Yapılan analizler sonucunda erkek öğrencilerin kadın öğrencilerden daha fazla riskli davranış sergiledikleri tespit edilmiştir. Ayrıca üniversite öğrencilerinde ahlaki uzaklaşma değişkeninden elde edilen puanın artması durumunda, riskli davranış tüm alt boyutlarında da artışa sebep olduğu tespit edilmiştir. Nitekim özel insandan algılanan sosyal desteğin artmasının bazı riskli davranışları arttırdığı, aile ve arkadaş desteğinin artmasının ise bazı riskli davranışları azalttığı tespit edilmiştir. Ahlaki uzaklaşma ve algılanan sosyal destek %28 ile %3 arasında riskli davranış alt boyutlarını açıklamaktadır.
Understanding the users and uses of UK Natural History Collections
Authors: Hardy Helen , Livermore Laurence , Kersey Paul , Norris Ken , Smith Vincent
Published: October 2023

UK natural science collections hold over 137 million items, an unrivalled source of data about 4.56 billion years of planetary development and hundreds of years of biological change, including the differences made by humans — but the scientific, commercial, and societal benefits of these collections are constrained by the limits of physical access, and by highly fragmented digitisation efforts with less than 10% digitally available. Following work with Frontier Economics in 2021, which showed potential for £2 billion in benefits to the UK economy from digitising all UK natural science collections, in 2022–23 the Natural History Museum London worked, with analytical support from McKinsey and Company, to understand the impact of what has already been digitised and shared by UK natural science collections — what is the demand for these data, what are they used for, and how does this deliver efficient, effective and impactful research?

This study focuses on usage via the Global Biodiversity Information Facility, the largest source of relevant usage data, examining 7.6 million records from twelve UK institutions. While these UK collections data are just 0.3% of total GBIF occurrences, they are cited in 12% of peer reviewed publications citing GBIF data, showing the disproportionate impact of UK collections data and the historical, geographical, and taxonomic richness that they bring. Researchers have already benefited from more than £18 million of efficiency savings from digital UK specimen data. Data from natural science collections held in the UK are uniquely impactful resources, vital to a future in which people and planet thrive, and a step change in the pace of digitisation is needed to unlock their potential for researchers, policymakers, and society.
Les récompenses monétaires individuelles fondées sur les résultats des managers sont-elles nécessaires pour le pilotage de la performance ?
Authors: Meyssonnier François , Tarafi Nadim
Published: October 2023

Une étude exploratoire comparée des modes d’incitation des managers à la réalisation des objectifs économiques et opérationnels de neuf entreprises de l’ouest de la France est réalisée. Les dispositifs de récompenses monétaires et non monétaires et leur perception par les managers sont analysés à partir de 37 entretiens. Il est montré que les dispositifs pratiques d’intéressement des managers sont souvent collectifs, peu discriminants et basés plus sur les efforts et les comportements que sur les résultats. Le rôle des rémunérations individuelles et variables fondées sur l’atteinte des objectifs dans la motivation extrinsèque des managers intermédiaires semble donc limité.

Cet article traite de la relation transatlantique telle qu’elle s’est développée depuis l’investiture de Joe Biden, et tout particulièrement depuis l’invasion totale de l’Ukraine par la Russie en février 2022. De nombreux espoirs ont été placés dans le nouveau Président américain après l’expérience déconcertante que fut celle de Donald Trump. Toutefois, la première année de mandat de Biden n’a pas été un franc succès. Le retrait chaotique d’Afghanistan a laissé un goût amer à de nombreuses personnes en Europe, tandis que les Européens n’ont toujours pas tenu les engagements contractés lors du sommet du Pays de Galles de 2014 en matière de réarmement. Pourtant, la décision de Vladimir Poutine de lancer une invasion à grande échelle de l’Ukraine a galvanisé l’ancienne alliance, et un nouveau sens commun des objectifs a émergé dans la tentative de contrer l’agression russe. Les Américains ont renforcé leur présence en Europe ; les Européens ont commencé à renforcer leurs défenses ; les livraisons d’armes de pointe à l’Ukraine se sont accélérées ; l’UE a fait preuve d’une grande fermeté en imposant des sanctions sévères à la Russie, quitte à en subir des conséquences économiques. Reste à savoir si cette nouvelle cohérence transatlantique peut être maintenue, mais en l’état, le Kremlin a donné un nouveau souffle à l’alliance transatlantique.
Pie XII et l’Amérique latine, entre panlatinisme catholique et Occident chrétien

Published: October 2023

Le Traité du Quirinal, signé à Rome le 26 novembre 2021 et entré en vigueur le 1 er  février 2023, souligne la volonté politique d’une coopération renforcée entre la France et l’Italie. Parmi ses onze articles thématiques, le deuxième concerne les aspects de sécurité et de défense. Le renforcement de la coopération politicomilitaire ne peut commencer que par une meilleure compréhension mutuelle. L’objectif de cet article est précisément de comprendre le système politico-militaire italien, en soulignant ses similitudes et ses différences par rapport à son homologue français, afin de renforcer la coopération en tirant parti des atouts communs, et en notant les limites et les contraintes mutuelles, pour parvenir à une approche complémentaire en vue de la réalisation d’objectifs communs.
Lutter contre les rétroactions sur le territoire national : quel rôle pour la Gendarmerie nationale ?
Authors: Vieillard-Baron Tugdual
Published: October 2023

L’éventualité d’un engagement majeur de la France dans un conflit international rend nécessaire de repenser la défense du territoire, marquée depuis plusieurs décennies par la seule lutte contre le terrorisme. Il s’agit de redécouvrir, en les actualisant, les concepts de la guerre froide pour faire face aux menaces multiformes posées par les « rétroactions ». Trait d’union naturel entre les missions de défenses civile et militaire, la Gendarmerie offrira aux décideurs des capacités spécifiques qui lui permettront d’épauler utilement les Armées dans cette mission. Pour en garantir l’efficacité, le cadre juridique, la coordination et la gouvernance devront faire l’objet d’une attention particulière des autorités politiques, sur le plan central comme sur le plan local.

Écrire l’histoire de résistances graphiques : graffitis d’insurgés prisonniers au mitan du 19 e siècle
Authors: Fureix Emmanuel
Published: October 2023

Les graffitis révolutionnaires du 19 e siècle ont laissé peu de traces. Elles se concentrent surtout dans les lieux de détention des insurgés, dans un après-coup. L’article propose à la fois une réflexion historiographique sur les manières de « faire parler » des graffitis politiques récemment patrimonialisés et une enquête de terrain sur deux sites de graffitis de la Deuxième République : le château d’If et la tour de Crest (Drôme). Il esquisse une pragmatique de l’écriture protestataire. Les graffitis étudiés transforment l’espace et le temps carcéral ; ils affirment des identités à la fois individuelles et collectives, dans une communauté d’épreuves ; ils subvertissent les normes disciplinaires tout en respectant une zone grise de tolérance négociée.
Citations et circulations révolutionnaires dans les graffitis contemporains (France)
Authors: Larrère Mathilde
Published: October 2023

Depuis 2016, les mobilisations sociales sont marquées par un recours quasi systématique et croissant au « braconnage de l’espace public » par des graffitis, ou des affichages sauvages. Ces mêmes mouvements charrient, assument diverses références mémorielles à l’histoire longue des luttes. Aussi, un certain nombre de graffitis citent-ils explicitement des révolutions du passé. En s’appuyant sur un corpus de clichés, majoritairement personnels, inédits, l’article présente et interroge l’inscription sur les murs des imaginaires révolutionnaires au cœur des mouvements contemporains, des citations à la Commune sur les places de Nuit debout en 2016 aux graffiti des Gilets jaunes évoquant la Révolution française, en passant par les références ambivalentes à mai 68.

Pro-Environmental Behaviors and Environmental Improvement
Authors: Lin Boqiang , Wei Kai
Published: October 2023

Fostering pro-environmental behaviors (PEBs) among the young generation is imperative. Based on a micro-survey of Chinese college students, the authors used Logit and ordered Logit model to obtain empirical information on perceived past environmental quality and current PEBs. The authors found that environmental improvement positively impacted various PEBs, including green travel, plastic bag use, garbage sorting, and energy conservation. Better perceived environmental quality leads to increased environmental expectations, motivation to adopt PEBs, and awareness of environmental responsibility. The positive effect is more pronounced for individuals engaged in environmental protection activities, familiar with environmental advocacy, and with a family consensus on environmental protection. These findings were corroborated through robustness tests of alternative methods, samples, and measures. There is a positive feedback loop between a sustainable environment and human behavior. Policy recommendations are offered to further strengthen this symbiotic relationship.

Published: October 2023

Global plastic production and consumption have increased due to its outstanding properties. Their widespread use is cause for concern, as most plastics deteriorate but never fully decompose, posing a risk to ecosystems. A large source of ocean plastic waste is "ghost gear", a result of intentional or accidental abandonment of fishing gear at sea. To reduce their impact, mechanical recycling is considered a viable option as it is an efficient recycling method in terms of time, cost-effectiveness, and environmental impact. This study aims to investigate the feasibility of producing injection moulded components from recycled fishing nets composed of polyamide 6 (PA6). The degradation in a marine environment allied with the mechanical recycling process was evaluated by comparing the physical and mechanical properties of injection moulded specimens of both recycled fishing nets and commercially available extruded PA6 plates. In addition, both materials were subjected to an additional mechanical recycling step (after the injection) to determine the impact on the properties of additional recycling cycles. Finally, the feasibility of injection moulding of cardholders was also studied. The physical and mechanical characterization concluded that the property values obtained in the tensile test and the density measurements of the recycled fishing nets are within the range of values established for the properties of an extruded, non-recycled PA 6, and that the effect of the second recycling on its properties was negligible. The marine degradation had a more significant impact on the tensile properties and Charpy notched impact strength than on the hardness and density values.

Authors: Gonçalves Lucas S. , Campilho Raul D.S.G. , Prakash Chander
Published: October 2023

The Automotive Industry is in constant evolution, thanks in part to its high level of production and customer demands for quality assurance. New processes, equipment and products are constantly emerging, leading to new vehicles launched to the public. These processes and equipment need adequate monitoring tools and forms of quality assurance, and it is the responsibility of the engineering department to look for economically viable and efficient ways of guaranteeing the quality of products in an industry where quality itself is considered one of its pillars. This work aims to develop and validate a solution for quality control in the automotive industry while taking full advantage of the technological factors provided by the equipment used. It deals with researching and applying a three-dimensions (3D) scanner in product quality monitoring tasks of a door panel manufacturing process. Pilot studies were carried out to assess the real capabilities of the equipment and determine problems that could arise when scaling the process for a real production of car door panels. The implementation and final results are also described in this work, showing that it is possible to develop a flexible equipment with multiple applications and apply it in the automotive industry.
Experimental studies and mathematical modeling of the viscoelastic rheology of tracheobronchial mucus from respiratory healthy patients
Authors: Tauwald Sandra Melina , Michel Johanna , Brandt Marie , Vielsmeier Veronika , Stemmer Christian , Krenkel Lars
Published: October 2023

Background: Tracheobronchial mucus plays a crucial role in pulmonary function by providing protection against inhaled pathogens. Due to its composition of water, mucins, and other biomolecules, it has a complex viscoelastic rheological behavior. This interplay of both viscous and elastic properties has not been fully described yet. In this study, we characterize the rheology of human mucus using oscillatory and transient tests. Based on the transient tests, we describe the material behavior of mucus under stress and strain loading by mathematical models. Methods: Mucus samples were collected from clinically used endotracheal tubes. For rheological characterization, oscillatory amplitude-sweep and frequency-sweep tests, and transient creep-recovery and stress-relaxation tests were performed. The results of the transient test were approximated using the Burgers model, the Weibull distribution, and the six-element Maxwell model. The three-dimensional microstructure of the tracheobronchial mucus was visualized using scanning electron microscope imaging.Results: Amplitude-sweep tests showed storage moduli ranging from 0.1 Pa to 10000 Pa and a median critical strain of 4 %. In frequency-sweep tests, storage and loss moduli increased with frequency, with the median of the storage modulus ranging from 10 Pa to 30 Pa, and the median of the loss modulus from 5 Pa to 14 Pa. The Burgers model approximates the viscoelastic behavior of tracheobronchial mucus during a constant load of stress appropriately (R2 of 0.99), and the Weibull distribution is suitable to predict the recovery of the sample after the removal of this stress (R2 of 0.99). The approximation of the stress-relaxation test data by a six-element Maxwell model shows a larger fit error (R2 of 0.91).Conclusions: This study provides a detailed description of all process steps of characterizing the rheology of tracheobronchial mucus, including sample collection, microstructure visualization, and rheological investigation. Based on this characterization, we provide mathematical models of the rheological behavior of tracheobronchial mucus. These can now be used to simulate mucus flow in the respiratory system through numerical approaches.

The Impact of Team Triage Method on Emergency Department Performance Indexes: A quasi-interventional study
Authors: Yousefi Zhila , Feizollahzadeh Hossein , Shahsavarinia Kavous , Khodadadi Esmail
Published: September 2023

Introduction:

One of the effective methods of patient triage in the emergency department (ED) is the use of team triage, including physicians and nurses. Considering that there is no conclusive evidence about the effectiveness of team triage, this study aimed to investigate the effect of the team triage method on ED performance indexes.

Methods:

The present study is a quasi-interventional study in which 200 patients were referred to the ED in the hospitals of Tabriz in 2020. Participants were randomly assigned to two groups (team triage and conventional triage) and were evaluated. Data were collected by a three-part questionnaire including the participants’ demographic characteristics, the five-level triage form, and Press-Ganey satisfaction questionnaire were used. Data were analyzed by SPSS.22 statistical software.

Results:

The results showed that the mean score of waiting time for the first physician visit in team triage was statistically significantly lower than the conventional triage (P = 0.001). Furthermore, the mean score of waiting time for receiving the first treatment in team triage was statistically significantly lower than the conventional triage (P = 0.001). Finally, the mean score of patients’ satisfaction in team and conventional triage was statistically significantly higher in team triage (P = 0.001).

Conclusion:

The study findings revealed that the team triage method, in comparison to conventional triage, decrease the waiting time for receiving the first service and length of stay, but leads to more patient’s satisfaction. Therefore, to improve the performance indicators of the ED, it is recommended that hospital managers use the team triage method.

Published: September 2023

Encapsulated fat necrosis (EFN), most commonly, is an asymptomatic entity and is often found incidentally in images. However, in the abdomen, it may present as an acute abdomen. Mesenteric fat necrosis is part of a larger disease spectrum called collectively mesenteric sclerosis. It results in forming of a mass that can be confused with other pathologies such as liposarcoma, carcinoma of the cecum, and other more benign conditions such as appendagitis of the epiplon. We present the case of an 82-year-old male who presented with an asymptomatic right lower quadrant mass with concerning computed tomography findings with no previous abdominal surgery or trauma history. Diagnosing EFN is crucial as it can mimic bowel cancer and immune-related mesenteric pathology such as sclerosing mesenteritis, the management of which is far more extreme and aggressive than EFN.

Mucocele of the sphenoid sinus is one of the rare diseases which an ENT surgeon can encounter in a clinical setup. It can often present as a chronic headache. It can remain undiagnosed unless a symptom due to the compression effect of the mucocele, such as diminution of vision, ophthalmoplegia, or any intracranial complication, occurs. Early diagnosis and emergency surgical intervention are imperative to prevent complications. Although late presentation can have a risk of permanent vision loss, improvement in vision postsurgery does not necessarily depend on the duration of symptoms. Here, we present a rare case scenario where, even after the delayed presentation, the patient had a significant vision improvement postsurgery.

Published: September 2023

Background:

Carcinoma penis is more common in India compared to the West. The role of chemotherapy in carcinoma penis is ambiguous. We analyzed the profile and outcomes of patients with carcinoma penis treated with chemotherapy.

Methods:

We analyzed the details of all patients with carcinoma penis treated at our institute between 2012 and 2015. We collected particulars regarding demography, clinical presentation, treatment details, toxicities, and outcomes of these patients. Event-free and overall (OS) survival were calculated from the time of diagnosis until documentation of disease relapse/progression or death for the patients with advanced carcinoma penis who were eligible for chemotherapy.

Results:

There were 171 patients with carcinoma penis treated at our institute during the study period including 54 (31.6%) patients with stage I, 49 (28.7%) patients with stage II, 24 (14.0%) patients with stage III, 25 (14.6%) patients with stage IV, and 19 (11.1%) patients with recurrent disease at presentation. The present study included 68 patients with advanced carcinoma penis (stages III and IV) who were eligible for chemotherapy, with a median age of 55 years (range: 27–79 years). Sixteen patients received paclitaxel and carboplatin (PC) and 26 patients cisplatin and 5-FluoroUracil (CF). Neoadjuvant chemotherapy (NACT) was given to four patients with stage III and nine patients with stage IV disease. Of the 13 patients given NACT, we observed a partial response in five (38.5%), stable disease in two (15.4%), and progressive disease in five (38.5%) evaluable patients. Six (46%) patients underwent surgery after NACT. Only 28/54 (52%) patients received adjuvant chemotherapy. After a median follow-up of 17.2 months, the 2-year OS rates were 95.8, 89, 62.7, 51.9, and 28.6% for stages I, II, III, IV, and recurrent disease, respectively. The 2-year OS of patients who were given chemotherapy versus those who were not given chemotherapy were 52.7 and 63.2%, respectively (P = 0.762).

Conclusions:

We report the real-world outcomes of two chemotherapeutic regimens used in consecutive patients with advanced carcinoma penis. Both PC and CF seemed effective and safe. However, approximately half of patients with advanced carcinoma penis do not receive the planned/indicated chemotherapy. We need further prospective trials regarding the sequencing, protocols and indications of chemotherapy in this malignancy.
Acetic acid versus toluidine blue as screening tools for oral potentially malignant disorders
Authors: Winton Kalluvelil San Rose , Narayanan Veena S.
Published: September 2023

Background:

Diagnostic adjuncts such as toluidine blue have been investigated as screening tools that improve visual examination of potentially malignant disorders (PMD) and oral cancer. Acetic acid has been reported to be of value in the early detection of cervical cancers. This study assessed the utility of 5% acetic acid as a diagnostic adjunct in oral PMD and compared the accuracy of acetic acid with toluidine blue in the detection of dysplastic PMD and high-risk lesions.

Materials and Methods:

This cross-sectional study was conducted at a dental hospital in a rural setting. Thirty-one patients with oral PMD formed the study group. Five percent acetic acid was applied to the lesions, followed by toluidine blue application and biopsy. Sensitivity, specificity, and positive and negative predictive values were computed considering true positives as stain uptake in dysplastic and high-risk PMD.

Results:

The sensitivity, specificity, and positive and negative predictive values of acetic acid for identifying dysplastic or malignant lesions were 100%, 13.3%, 51.2%, and 100%, respectively, and that for toluidine blue were 75%, 100%, 100%, and 78.9%, respectively. The corresponding values for identifying high-risk PMD (lesions with moderate and severe dysplasia) using acetic acid were 100%, 9.1%, 25.9%, and 100%, respectively, and for toluidine blue were 85.7%, 81.8%, 60%, and 94.7%, respectively.

Conclusion:

The utility of acetic acid in detecting dysplasia and high-risk PMD is severely limited due to its poor specificity. Compared with acetic acid, toluidine blue is a superior screening tool.
Time Spent in Physical Activity by Ambulatory Stroke Patients and its Comparison Based on Gait Speed – A Pilot Study
Authors: Soni Mansi , Muruganantham Balaganapathy
Published: September 2023

Introduction:

Physical activity is proven to have beneficial effects in the prevention and management of stroke. This makes it an important modifiable risk factor Stroke is a condition resulting in various functional deficits. The higher functional ability of stroke patients may result in their higher physical activity. Gait speed is a functional parameter to differentiate between the ability of mobility of patients with stroke. However, if it is reflected in the time spent in an activity needs to be explored.

Objectives:

This pilot study attempts to explore time spent in PA by ambulatory stroke patients and compare time spent in different activity levels based on gait speed.

Subjects and Methods:

This pilot study recruited 26 ambulatory patients with stroke after obtaining informed consent. Their PA was recorded with ActiGraph wGT3X-BT for 1 day. Differences in time spent in the different level of PA were compared between people with gait speed ≤0.49 m/s and >0.49 m/s.

Results:

The result of the study shows that patients with stroke having gait speed ≤0.49 m/s had higher time spent in sedentary (686.02 ± 80.35 min/day) and light activity (612 ± 69.84 min/day) as compared to those with >0.49 m/s (646.42 ± 137.52 min/day and 593.57 ± 119.95 min/day, respectively). While time spent in moderate activity was higher in patients with stroke having gait speed >0.49 m/s (199.73 ± 111.17 min/day) as compared to those whose gait speed was ≤0.49 m/s (141.84 ± 76.75 min/day). However, this difference failed to demonstrate statistical significance.

Conclusion:

Patients with stroke were less physically active as compared to recommendations. Gait speed-based comparison demonstrates a nonsignificant difference between both groups. This suggests that factors other than gait speed may contribute to ambulatory stroke patients’ time spent in PA.

Breast cancer is the most common cancer worldwide. As per GLOBOCAN 2020, female breast cancer is the most commonly diagnosed cancer (11.7% of total cases). In India, like any other cancer, breast cancer patients present late to the clinic with more than 60% presenting in Stage 3rd and 4th, of these 25% of locally advanced breast cancers develop a fungating breast lesion causing significant distress for the patient, physically, mentally, as well as socially. The subset of patients with locally advanced fungating mass poses a big challenge to the treating surgeon. In this case report, a locally advanced fungating breast cancer weighing 7.5 kg was removed by surgery.

Published: September 2023

Multiple myeloma is characterized by the neoplastic proliferation of plasma cells producing a monoclonal immunoglobulin. Presenting signs and symptoms of multiple myeloma include bone pain, pathologic fractures, weakness, anemia, infection, hypercalcemia, spinal cord compression, and renal failure. It is rare for a myeloma to present with a mediastinal mass. Here we report a case which presented as a mediastinal mass with acute kidney injury which on evaluation turned out to be extramedullary plasmacytoma with coexisting Multiple myeloma. Early diagnosis is essential for the prompt management of Multiple myeloma.
Raised Left Dome

Published: September 2023

Eventration of diaphragm radiologically presents as raised dome. Eventration can be acquired or congenital. Symptoms may vary from mild or no symptoms, symptoms of gastroesophageal reflux disease, dyspnea, chronic cough, recurrent respiratory infection, palpitation, and chest pain. Thoracic ultrasound is useful in differentiating eventration from other causes for raised dome. In asymptomatic patients and those with mild symptoms with low risk for complications, treatment is conservative. Surgical plication of diaphragm is indicated if patients are symptomatic or at high risk of developing complications.
