Diagnostic Dilemma

Osteoblastoma is a benign neoplasia and is uncommon in the jaws. In some cases, this lesion presents extremely aggressive local characteristics and is termed aggressive osteoblastoma. Because the clinical, radiographic and histopathologic characteristics are similar to those of a variety of benign and malignant tumors, it poses a diagnostic dilemma. This report presents a case of an aggressive osteoblastoma in the mandible and discusses the differential diagnosis of this lesion. A 13-year-old white male sought the Stomatology Clinic at the State University of Paraíba, Campina Grande, PB, Brazil, complaining of asymptomatic swelling on the left side of his face. Cone-beam computerized tomography showed a multilocular, hypodense bone lesion, located in the body of the left mandible and lower third of the ascending ramus. The initial diagnostic hypothesis was juvenile ossifying fibroma or osteosarcoma. After histopathologic examination, the final diagnosis was aggressive osteoblastoma. Surgical resection with a safety margin was performed. There was no evidence of recurrence after a follow-up period of 4 years.

Abstract Lesions denominated fibro-osseous lesions of the jaw constitute a diversified group of disorders, in which the normal bone architecture is replaced by fibroblasts, collagen fibers and immature bone. At present, the World Health Organization recognizes four variants of these lesions, namely: bone-cement dysplasia, fibrous dysplasia, ossifying fibroma and Familial gigantiform cementoma. Fibrous dysplasia may present in the monostotic form, affecting one single bone or an isolated craniofacial region; and in the Polyostotic form, involving two or more bones of the skeleton, and eventual association with syndromic conditions. The patient, C.P.G., 43 years old, sought attendance due to symptomatic increase in the region of the mandibular body on the right side. Imaging exams revealed craniofacial areas with ground-glass aspect, beyond the extensive mandibular radiolucent lesion. During the physical exam, spots of the Café au lait type disposed on the right side of the body were identified, in addition to uncoordinated gait with distinct shortening of the right leg. Additional radiographic exams showed evidence of skeletal dissemination of the disease. The patient denied any sexual precocity, and the final diagnosis was fibrous dysplasia, expressed by means of the Jaffe-Lichtenstein syndrome, in association with a simple bone cyst.

Endometriosis is a common entity among fertile women which unfortunately manifests through variable symptomatology. Intestinal involvement in endometriosis is quite common and can simulate several diseases such as Crohn’s disease, appendicitis, tubo-ovarian abscess, or malignant tumors. Intestinal obstruction due to endometriosis is rare, and preoperative diagnosis is difficult because the signs and symptoms are nonspecific and can be easily confused. In the case of patients without a history of endometriosis, diagnosis is further complicated. We present a case of a 41-year-old female patient. She presented to the emergency room with complete bowel obstruction and a mass in the cecum. Surgery was decided, and the patient underwent full recovery. Endometriosis was the final diagnosis for the observed condition.

Wegener’s granulomatosis is a systemic disease characterized by a granulomatous lesion that can affect any organ throughout the body.This case-report illustrates the problem posed by a patient presenting with bilateral serous otitis media with marked sensorineural hearing loss, facial nerve paralysis and an atypical serological picture. The importance of early diagnosis and the protocol for the management of a patient with an uncertain diagnosis is discussed. Due to atypical presentations, only a high index of suspicion will ensure an early diagnosis.

Histopathological Investigation

The finding of a colloid cyst on neuroimaging is often incidental. These lesions are usually located at the foramen of Monro, are hyperdense on CT scans, and generally demonstrate signal intensity of water on MR images, although this depends on their content. When symptomatic, they frequently present with headaches and nausea due to an obstructive hydrocephalus. The authors describe a case of a giant colloid cyst in a patient presenting with complete left-sided vision loss and progressive memory loss, two very atypical findings in colloid cyst presentation. Imaging findings were also atypical, and this case proved to be a diagnostic dilemma because of its clinical and radiological presentation. Histopathological investigation was of utmost importance in the final diagnosis of a colloid cyst. To the authors' knowledge this colloid cyst is larger than any other described in the literature.

The Real

David McNally styles this book as beginning in a polemic and ending in a “materialist approach to language” much indebted to the German critic Walter Benjamin. The charge is that “postmodernist theory, whether it calls itself poststructuralism, deconstruction or post-Marxism, is constituted by a radical attempt to banish the real human body—the sensate, biocultural, laboring body—from the sphere of language and social life” (p. 1). By treating language as an abstraction, McNally argues, postmodernism constitutes a form of idealism. More than that, it succumbs to and perpetuates the fetishism of commodities disclosed by Marx insofar as it treats the products of human laboring bodies as entities independently of them. Clearly irritated by the claims to radicalism made by those he labels postmodern, McNally thinks he has found their Achilles' heel: “The extra-discursive body, the body that exceeds language and discourse, is the ‘other’ of the new idealism, the entity it seeks to efface in order to bestow absolute sovereignty on language. To acknowledge the centrality of the sensate body to language and society is thus to threaten the whole edifice of postmodernist theory” (p. 2).

Target Organs

Metastatic diffusion is thought to be a multi-step phenomenon involving the release of cells from the primary tumor and their diffusion through the body. Currently, several hypotheses have been put forward in order to explain the origin of cancer metastasis, including epithelial–mesenchymal transition, mutagenesis of stem cells, and a facilitating role of macrophages, involving, for example, transformation or fusion hybridization with neoplastic cells. In this paradigm, tumor-secreted extracellular vesicles (EVs), such as exosomes, play a pivotal role in cell communications, delivering a plethora of biomolecules including proteins, lipids, and nucleic acids. For their natural role in shuttling molecules, EVs have been newly considered a part of the metastatic cascade. They have a prominent role in preparing the so-called “tumor niches” in target organs. However, recent evidence has pointed out an even more interesting role of tumor EVs, consisting in their ability to induce malignant transformation in resident mesenchymal stem cells. All in all, in this review, we discuss the multiple involvements of EVs in the metastatic cascade, and how we can exploit and manipulate EVs in order to reduce the metastatic spread of malignant tumors.

Background: Soft tissue sarcomas are a rare and heterogeneous group of malignant tumors of mesenchymal origin that comprise less than 1 percent of all adult malignancies. Although they occur anywhere in the body, they involve most commonly in extremities, trunk, retroperitoneum and head and neck. The aim of the study was to analyze clinical and histopathological features of various soft tissue sarcomas.Methods: This was a retrospective study, conducted in tertiary cancer centre in Odisha during the period 2015 to 2018. We collected clinical parameters like age, sex, site of swelling, any associated pain and biopsy reports and these variables were correlated with final histopathology reports.Results: A total of 107 patients were included in the study, with male to female ratio of 2:1(71 and 36) and average age of 43.45 years. All of them presented with a swelling. The lower extremities were the most common sites i.e. 44.62%. Pleomorphic sarcoma was the most frequent histologic variety comprising 43% and less frequent variety were angiosarcoma, and myxoid sarcoma.Conclusions: Soft tissue sarcoma are predominant in males and middle aged population are frequently affected. Most common affected site is lower extremity and pleomorphic sarcoma is the prominent histologic type.

Psychophysiological State

This paper examines the dynamics of changes in the indicators of the psychophysiological state of students of the Siberian State University of Railway Transport. The indicators of motor activity, vital index (ZHI) and respiratory system were considered. The purpose of the study is to identify the physical and functional capabilities of the body of first-year students, as well as to analyze the level of health. The objectives of the study are to determine the level of psychophysiological state of students in dynamics. Research hypothesis: the source of physical education should be on motor activity that is appropriate for development, in order to promote self-efficacy and pleasure, as well as encourage continuous participation in physical activity; through the acquisition of motivational experience by students in physical education and sports, physical and functional development is achieved, as well as self-esteem, goal orientation and tasks; the effectiveness of physical development can be achieved by changing the approaches to the implementation of FC programs, sports facilities, recruitment, as well as the organization of school-university continuity. Research methods: analysis, systematization, generalization. The results of the research showed a decrease in physical fitness and activity in general, as well as the need to develop motor abilities and improve the level of physical health of students.
