Delayed malignant melanoma recurrence simulating primary ovarian cancer: Case report

BACKGROUND: Metastatic involvement of the ovary from malignant melanoma is uncommon and presents a diagnostic challenge. Most cases are associated with disseminated disease and carry a dismal prognosis. Delayed ovarian recurrences from melanoma may mimic primary ovarian cancer and lead to aggressive cytoreductive procedures. CASE PRESENTATION: A case of malignant melanoma in a premenopausal patient is presented with late abdominal and ovarian metastatic spread, where ascitic fluid cytology led to an accurate preoperative diagnosis and the avoidance of unnecessary surgical procedures. CONCLUSION: Secondary ovarian involvement is associated with a poor prognosis and efforts should be made for adequate palliation. Pathologic diagnosis with non-invasive procedures is crucial in order to avoid unnecessary surgery. Surgical interventions may be undertaken only in selected cases of limited metastatic disease, where complete resection is expecte

A review of pseudo-labeling for computer vision

Deep neural models have achieved state of the art performance on a wide range of problems in computer science, especially in computer vision. However, deep neural networks often require large datasets of labeled samples to generalize effectively, and an important area of active research is semi-supervised learning, which attempts to instead utilize large quantities of (easily acquired) unlabeled samples. One family of methods in this space is pseudo-labeling, a class of algorithms that use model outputs to assign labels to unlabeled samples which are then used as labeled samples during training. Such assigned labels, called pseudo-labels, are most commonly associated with the field of semi-supervised learning. In this work we explore a broader interpretation of pseudo-labels within both self-supervised and unsupervised methods. By drawing the connection between these areas we identify new directions when advancements in one area would likely benefit others, such as curriculum learning and self-supervised regularization

Exploring elements of an effective practitioner-patient relationship in dentistry

Purpose: The present study, having human-centered orientation (empathy) as an index of the doctor-patient relationship, aims to record the degree of user/patient satisfaction with the health services provided by the Department of Oral Medicine/ Pathology, Aristotle University of Thessaloniki.Materials and Methods: Quantitative analysis of the research was conducted using a four-item anonymous questionnaire on satisfaction: (a) communication (b) information/ awareness (c) respect/ acceptance and (d) interest/ understanding. The participants were 600 patients with oral diseases of various severity. Statistical analysis was performed using IBM Statistics SPSS 20 and 25.Results: The participants were 61.7% females (median age 58.5 years) and 38.3% males (median age 60 years). According to the scores the patients’ satisfaction was: a) communication (97.8%), (b) information/ awareness (85.8%), (c) respect/ acceptance (78.8%), and (d) interest/ understanding (67.7%).Conclusion: Quantitative analysis of the empirical study established that the patients of Department of Oral Medicine revealed a fairly high rate of satisfaction. However some service parameters (interest/ understanding) need further attention and for this reason improvement proposals have been tabled

The Impact of Religious Beliefs and Practices on Coping with Health Challenges Posed by Covid-19

In the midst of the Covid-19 pandemic, the aim of the present study was to investigate to what extent the undergraduate students of the Department of Dentistry, Aristotle University of Thessaloniki, felt the need to come closer to their own religiosity, spirituality, or faith. Materials and methods: Empirical research was conducted by means of an anonymous questionnaire, comprising demographics and items focusing on religiosity, spirituality, and faith. The survey results were processed using “MICROSOFT EXCEL IBM SPSS STATISTICS 24” statistical processing software. Results:  To overcome health dilemmas, the wide majority of students did not focus on religious & spiritual practices (70% & 66.7%) while at the same time, their religiosity & spirituality was not enhanced (74% & 78%). However, for the same period, 53% of the students stated that their faith was enhanced. Conclusions: While overall students’ religiosity & spirituality indicators were low, for the same period they stated that their faith in overcoming health distress was strengthened, which triggers new questions and prompts further research in the field of humanities.&nbsp

Idiopathic Sweet’s Syndrome with Oral Manifestations: Case Report and Review of the Literature

Sweetov sindrom ili akutna febrilna neutrofilna dermatoza, rijetka je kožna bolest nepoznate etiologije i patogeneze, povremeno udružena s malignitetom, a najčešće se javlja kod sredovječnih žena. Klinički su to bolne papule koje oblikuju plakove na koži te ustrajna vrućica i bolni zglobovi, a najdosljedniji je laboratorijski nalaz leukocitoza s neutrofilijom. Predstavljamo dobro dokumentiran slučaj pacijentice u dobi od 62 godine s idiopatskim Sweetovim sindromom, prvim prijavljenim slučajem s oralnim lezijama u Grčkoj te opisom kliničkih i histoloških nalaza i terapije. Također dajemo uvid u literaturu o slučajevima koji uključuju i oralne lezije.Sweet’s syndrome or acute febrile neutrophilic dermatosis is an uncommon skin disease of unknown cause and pathogenesis, occasionally associated with malignancy, which is mostly occurring in middle aged women. Clinically, painful plaqueforming inflammatory papules on the skin are accompanied by high persistent fever and arthralgia and the most consistent laboratory findings are peripheral leukocytosis with neutrophilia. We present a well-documented case of a 62 year-old female patient, with idiopathic Sweet’s syndrome, the first reported in Greece with oral lesions, describing its clinical and histological findings and the treatment, and we also review the relative literature focusing on cases with oral involvement

SmartOrch: An Adaptive Orchestration System for Human-Machine Collectives

Web-based collaborative systems, where most computation is performed by human collectives, have distinctly different requirements from traditional workflow orchestration systems, as humans have to be mobilised to perform computations and the system has to adapt to their collective behaviourat runtime. In this paper, we present a social orchestration system called SmartOrch, which has been designed specifically for collective adaptive systems in which human participation is at the core of the overall distributed computation. SmartOrch provides a flexible and customisable workflow composition framework that has multi-level optimisation capabilities. These features allow us to manage the uncertainty that collective adaptive systems need to deal with in a principled way.We demonstrate the benefits of SmartOrch with simulation experiments in a ridesharing domain. Our experiments show that SmartOrch is able to respond flexibly to variation in collective human behaviour, and to adapt to observed behaviour at different levels. This is accomplished by learning how to propose and route human-based tasks, how to allocate computational resources when managing these tasks, and how to adapt the overall interaction model of the platform based on past performance. By proposing novel, solid engineering principles for these kinds of systems, SmartOrch addresses shortcomings of previous work that mostly focused on application-specific, non-adaptive solution
