Solitary Osteogenic Exostosis of the Femur Revealed by Recurring Acute Distal Thigh Pain: About a Case

Introduction: Solitary exostoses are the most common benign tumors of the fertile metaphyses of the long bones of children. Their radiological diagnosis of metaphyseal bone growth must be confirmed on pathological examination. These tumors can remain asymptomatic for a long time and reveal themselves during a particularly vascular complication. The objective of this study was to describe the epidemiological, diagnostic, therapeutic and evolutionary aspects of these tumors. Patient and Observation: We report the case of a 15-year-old adolescent girl, with no particular pathological history, received in the pediatric surgery department of the Donka National Hospital (HND) of the Conakry University Hospital for recurrent acute painful swelling of the lower third of the left thigh in an afebrile context accompanied by lameness and stopping school for a few days (2 - 3 days). The symptoms appear to have evolved over the past 3 years and after physical activities. It regresses with rest, analgesics and non-steroidal anti-inflammatory drugs. The notion of trauma and sickle cell disease was not reported in the patient's clinical history. It is the persistence of the symptomatology which motivates the said consultation. On palpation, a small hard mass is noted at the expense of the internal metaphysis of the left distal femur. Deep palpation of this area causes a tingling sensation and during rapid mobilization of the knee. The remainder of the orthopedic examination was unremarkable. Standard x-ray of the femur shows a bony growth with a pointed tip from the distal metaphysis of the left femur. On surgical exploration, we noted a wedge-shaped exostosis oriented towards the vastus medialis muscle. Histological examination of the surgical specimen confirms osteogenic exostosis. There is no recurrence after 2 years. Conclusion: The distal femoral metaphysis is the most common location of solitary osteochondromas in children. Their definitive diagnosis requires the histology of the surgical specimen. Only symptomatic exostoses should be operated on in children.

Information Management: Knowledge, Emancipation, and Metaphysics in the 21st Century

This text is trying to discuss an approximation to the concept of human emancipation,as part of our well-being,in terms of Education and Knowledge.Without abandoning our metaphysical perception of wholeness,as an extension of the continuity principle which connects our conscious and unconscious world,emancipation is considered as a personal struggle against all oppressions.Some of these are grounded in our inner world.In accordance with the Enlightenment request,reasoning and knowledge can help us to structure new forms of acceptances which are shaping our own emancipatory meaning.Under the impact of social influence and personal interpretation,the perceived knowledge is considered as a mental tool containing an upgraded valid information.Taking under consideration that this validity is not able to overcome the metaphysical origins of human thought,it is suggested that when this mental tool is functioning in a self-transformative,self-constructed,and flexible form,human intelligence is structuring a compatible information management mechanism,which can enable us to formulate our personal acceptances,bridge our empirical and hyper-empirical inner world,and enlighten our request for self-criticism,self-determination,and above all emancipation.

Is metaphyseal ulnar shortening osteotomy superior to diaphyseal ulnar shortening osteotomy in the treatment of ulnar impaction syndrome?A meta-analysis

BACKGROUND Although metaphyseal ulnar shortening osteotomy(MUSO)is safer for the treatment of ulnar impaction syndrome(UIS)than diaphyseal ulnar shortening osteotomy(DUSO),DUSO is widely used for UIS treatment.AIM To evaluate the effectiveness of DUSO and MUSO for UIS treatment and determine the factors that should be considered when choosing surgical treatment for UIS.METHODS Articles comparing the effectiveness of DUSO and MUSO for UIS treatment were systematically retrieved from MEDLINE(Ovid),PubMed,EMBASE,and Cochrane Library.The demography,incidence of complications,secondary operation rate,postoperative DASH score,wrist pain on the visual analogue scale,and grip strength improvement were also evaluated.In addition,the correlation between the improvement of grip strength and the shortening of osteotomy length of ulna was analyzed.The outcome of the patient was discontinuous,and the odds ratio,risk ratio(RR),and 95%CI were calculated and analyzed via RevMan5.3 software.RESULTS Six studies,including 83 patients receiving MUSO(experimental group)and 112 patients receiving DUSO(control group),were included in the meta-analysis.The second operation rate was significantly higher after DUSO than after MUSO.The DASH scores were slightly lower in the MUSO group than in the DUSO group.The patients receiving MUSO had slightly better pain relief effect than patients receiving DUSO.However,the incidence of complications and improvement of grip strength were not significantly different between the two groups.CONCLUSION Although DUSO and MUSO provide similar effects for UIS,MUSO is associated with a lower secondary operation rate,slightly lower postoperative DASH scores and slightly better pain relief effect than DUSO,indicating that MUSO can effectively be used for UIS treatment.

Pure Materials Contracts and Dependencies

The discourse on spirit versus materials delves into the exploration of human nature and the comprehension of human existence,particularly in the realms of free will,consciousness,and the search for meaning.Materialists assert that consciousness is a product of physical processes.Kant argues that consciousness actively constructs our reality,challenging materialist reductionism;Chalmers points out the hard problem of consciousness,highlighting the inadequacy of physical explanations for subjective experience.This paper continues the panpsychism,suggests that materials possess an attribute of“weak consciousness”,implying a fundamental consciousness inherent in materials that interact with human consciousness,the idea that the meaning of human existence can be based on another kind of dependency relationship;Feuerbach advocates for a materialistic view that prioritizes human physical existence,questioned the empirical validity of spiritual origins.

Tales de Miletus,Hegel,and the Theory of Everything

The author takes how focus of your reflection the no achievement of the Theory of Everything in the Whole,he indicates that the cause of that frustrated attempts it is the basis of construction of the thought used to,lay emphasis on the inadequacy of the thought supported in the metaphysical from material basis,with roots in Tales de Miletus,in ruling to find a solution,and he presents the metaphysical from relational basis,proto-enunciated in the Hegel’s thought,like a possible foundation to think what can be capable to apprehend the effectiveness reality in the flow of its happen,so in the scope of the existence of phenomena infra nanos,so well,in the hyper macros events.

The Physical Universe and the Theoretical Value of Science:Reflections on the Thought of G.Leopardi

The essay has two main purposes.The first consists of discussing some literary and philosophical thoughts on the epistemological value of science by one of the most famous and celebrated poets in Italian literature,Giacomo Leopardi.The poet firmly believes in the cognitive power of science,capable of revealing false beliefs with the light of reason.However,in his mature reflections,what will radically change will not be the value of scientific activity itself,always admirably accepted,but rather its true salvific force.Leopardi was not a scientist,but he used the scientific culture of his time to critically address the great existential themes of man concerning nature and the universe.He had amply demonstrated a scientific culture since his youthful'History of Astronomy',which would reappear in many of his other literary works.His deep and meditative reflections on the nature of finite and infinite space and time are a clear and fruitful testimony to this.However,Giacomo writes icastically,reason alone is not enough;it needs imagination.The second concerns a first reconstruction of the influence that the philosophy of Enlightenment had on Leopardi’s thought especially in relation to these topics:atheism,rejection of providentialism and anthropocentrism,the conception of nature,the question of the relationship between human and animal intelligence,the rejection of metaphysics,the importance of scientific knowledge.

DEBRA: On the Unsupervised Learning of Concept Hierarchies from (Literary) Text

With this work, we introduce a novel method for the unsupervised learning of conceptual hierarchies, or concept maps as they are sometimes called, which is aimed specifically for use with literary texts, as such distinguishing itself from the majority of research literature on the topic which is primarily focused on building ontologies from a vast array of different types of data sources, both structured and unstructured, to support various forms of AI, in particular, the Semantic Web as envisioned by Tim Berners-Lee. We first elaborate on mutually informing disciplines of philosophy and computer science, or more specifically the relationship between metaphysics, epistemology, ontology, computing and AI, followed by a technically in-depth discussion of DEBRA, our dependency tree based concept hierarchy constructor, which as its name alludes to, constructs a conceptual map in the form of a directed graph which illustrates the concepts, their respective relations, and the implied ontological structure of the concepts as encoded in the text, decoded with standard Python NLP libraries such as spaCy and NLTK. With this work we hope to both augment the Knowledge Representation literature with opportunities for intellectual advancement in AI with more intuitive, less analytical, and well-known forms of knowledge representation from the cognitive science community, as well as open up new areas of research between Computer Science and the Humanities with respect to the application of the latest in NLP tools and techniques upon literature of cultural significance, shedding light on existing methods of computation with respect to documents in semantic space that effectively allows for, at the very least, the comparison and evolution of texts through time, using vector space math.

Metaethics(后伦理学)与Metaphysics(后物理学)——粗议中西哲学之异同及中国有无哲学的问题

与西哲以metaphysics为核心相对应 ,中哲以metaethics为核心。在西哲中 ,metaphysics不仅为西方的物理学、自然科学 ,而且也为其伦理学提供哲学基础。在中哲中 ,metaethics不仅为中国的伦理道德作出了哲学的论证 ,而且使中国大哲在探讨物理问题时也染上浓重的伦理学色彩。由此也决定了西哲认识论是物理型的 ,中哲认识论是伦理型的。两者之差异在于 ,西哲认识世界是为了改造世界征服世界 ,中哲认识世界是为了改造自己征服自己。这进一步使中西哲学各有一套独特的方法论 :与西哲的逻辑学和方法论相应 ,中哲的方法论即功夫论。中西哲学尽管类型不同 ,但都是关于人生智慧的学问 ,因此都是哲学。

“meta-”可以译为“元”吗?——与辜正坤先生商榷

辜正坤提出希腊语前缀"meta-"不能译为"元"。事实上,由于"meta-"和"metaphysics"的历史渊源和后者的强大影响力,"meta-"已经获得了"本初、本源"的新含义,因此,可以将"meta-"译为"元"。不过"meta-"作为希腊语前缀的本义,提醒我们应该根据具体的语境有针对性地翻译,而不可追求简单的整齐划一。

Metaphysics与形而上学

我们对metaphysics的理解已经远远背离了其"后物理学""元物理学"的本义,在今天,"形而上学"完全被异化为一个极具政治色彩的词语;但是作为一种哲学思维品质,metaphysics恰恰是中国人所缺乏的。在中国,这种缺乏导致了一种哲学元素的缺失,直接影响到了整个社会的文化心理。我们对metaphysics的正确理解,已经日益成为一个非常重要的问题。

On the Philosophical Ontology for a General System Theory

System is a very general concept and theoretically speaking, every problem encountered can be modeled as a system. Thus, the general system theory (GST) proposed by Bertalanffy (1968) and developed by many others e.g. Bunge (1977;1979;1983a;1983b) and Maturana and Varela (1980;1987) could be treated as a theory of everything (TOE). However, it is well-known that the present version of GST has not reached the level of TOE because it lacks a clear ontology. Currently, quantum mechanics (QM), Newtonian mechanics (NM) and general relativity (GR), suitable for microscopic, macroscopic and cosmic phenomena respectively are based on very different ontologies. In this paper, a unified ontology for the general system theory which could be applied to any scale from micro to cosmic is proposed. It is expected that this could lay a foundation to generalize GST to TOE.

Review on the conceits used in ＂The Sun Rising＂

＂The Sun Rising＂ is one of the most outstanding metaphysical poems of John Donne. After a general introduction about the metaphysical poetry and the author, this paper mainly aims to analyze the arresting and original conceits and images used in ＂The Sun Rising＂ and comment on their effect on expressing the author＇s feeling and reflecting his emotions.

浅议“形而上学”

当今学术界对于"形而上学"仍存在误解,有必要对"形而上学"一词重新进行追溯以消除此误解,澄清Metaphysics的含义。所以对西方哲学的了解不能只停留在概念和观点的层次上,而是应深入到它的深层本质中去。

Formally Deriving the Third Newton’s Law from a Pair of Nontrivial Assumptions in a Formal Axiomatic Theory “Sigma-V”

The article is devoted to hitherto never undertaken applying an almost unknown logically formalized axiomatic epistemology-and-axiology system called “Sigma-V” to the Third Newton’s Law of mechanics. The author has continued investigating the extraordinary (paradigm-breaking) hypothesis of formal-axiological interpreting Newton’s mathematical principles of natural philosophy and, thus, has arrived to discrete mathematical modeling a system of formal axiology of nature by extracting and systematical studying its proper algebraic aspect. Along with the proper algebraic machinery, the axiomatic (hypothetic-deductive) method is exploited in this investigation systematically. The research results are the followings. 1) The Third Newton’s Law of mechanics has been modeled by a formal-axiological equation of two-valued algebraic system of metaphysics as formal axiology. (Precise defining the algebraic system is provided.) The formal-axiological equation has been established (and examined) in this algebraic system by accurate computing compositions of relevant evaluation-functions. Precise tabular definitions of the evaluation-functions are given. 2) The wonderful formula representing the Third Newton’s Law (in the relevant physical interpretation of the formal theory Sigma-V) has been derived logically in Sigma-V from the presumption of a-priori-ness of knowledge. A precise axiomatic definition of the nontrivial notion “a-priori-ness of knowledge” is given. The formal derivation is implemented in strict accordance with the rigor standard of D. Hilbert’s formalism;hence, checking the formal derivation submitted in this article is not a difficult task. With respect to proper theoretical physics, the formal inference is a nontrivial scientific novelty which has not been discussed and published elsewhere yet.

A Brief Survey of the Metaphysical Poets

The article focuses on the brief study of the metaphysical poets,who were men of learning,and to show learning was their whole endeavor. The chief metaphysical poets include John Donne,Richard Crashaw,Andrew Marvell,George Herbert,and Henry Vaughan. They preferred wildly original images,puns,similes,and metaphors,which collectively are called metaphysical conceits. The term metaphysical implies the poetry is abstract and highly complicated. The group shares certain traits,but their themes,structures,and assorted tones in their poetry vary widely.

Insufficient lateral stem contact is an influencing factor for significant subsidence in cementless short stem total hip arthroplasty

BACKGROUND Subsidence is one of the concerning early complications in cementless femoral stem.Few publications have studied the influencing factors for subsidence in short cementless stems,due to their metaphyseal anchoring without diaphyseal invasion,they might demonstrate different subsidence patterns than with the conventional stems.AIM To analyze the factors associated with significant subsidence in short stems,including any radiographic parameters.METHODS The digitized radiographs of 274 consecutive short stem total hip arthroplasties were retrospectively reviewed.Subsidence,neck-filling ratio(NFR),seating height and lateral stem contact were evaluated after a minimum of two years follow-up.A threshold of subsidence>3 mm was considered a clinically significant migration.RESULTS For the entire cohort,subsidence occurred in 75 cases(27.4%)with the mean stem subsidence of 0.5 mm.(0-12.7,1.68).Twelve hips(4.4%)had significant subsidence(>3 mm).The univariate regression analysis demonstrated that age,diagnosis,BMI,Dorr’s type B,NFR,and seating height had no significant influence on significant subsidence,whereas insufficient lateral stem contact(≥1 mm)did have a statistically significant influence[Odds ratio(OR)=5.02;95%CI:1.3-18.9;P=0.017].The multivariate regression analysis also demonstrated that insufficient lateral stem contact was a statistically significant influencing factor(OR=5.5;95%CI:1.4-21.4;P=0.014).There was no femoral stem revision for aseptic loosening in our cohort.CONCLUSION This study demonstrated that insufficient lateral stem contact was a statistically significant influencing factor on significant subsidence.Therefore,it is a particularly important step to create proper lateral cortical contact when performing the short stem total hip arthroplasty.

Physical, Epistemological and Metaphysical Perspectives on Quantum Theory： Constructed Experience？

This paper will present questions from three perspectives about Quantum Mechanics （QM）： physics, epistemological, and metaphysical. The quantum phenomena do not fit with the parameters of classical physics, so a daily intuition on macroscopic world is dispensable when it is the quantum object investigated. This physical domain induces a new thinking, which requires also new concepts to describe such object. The QM is disturbing and stimulates epistemological reflections, as the issues of access about what is known; and metaphysical theme are not to be left behind with regard to QM： What would the quantum object to？ What is apprehended when this object is perceived, once considered the disturbing characteristics that constitute its physical description： interference and non-separability？ What is its nature？ This paper focuses briefly on the analysis of B. d＇Espagnat in Veiled Reality, which would represent the physical perspective of QT; for epistemological questions, one will resort to the Kantian conception of knowledge; and with regard to the metaphysical perspective, we will rely on an article by Professor J. B. Arenhart. It is necessary to note that the question that pervades in this paper is about if the experience in QM is built. Thus, we will try to seek clarity on the philosophical issues through QT, regarding the problems about the possibility of knowledge of the quantum object and its nature, and whether experience in this case is built. But furthermore, the QM instigates us to think whether metaphysics proceeds on the investigation of nature when it comes to the QM. And such a question is more than to have as problem as the scope of the description of physical data, but rather whether it makes sense or whether metaphysical research is pertinent to the QM.

Plato Revealed: Alexander of Aphrodisias and His Philosophical Historiography

Alexander of Aphrodisias’s Commentary on Aristotle’s Metaphysics is an important testimony to understand Plato’s philosophy.In fact,Alexander uses some lost Aristotelian books,especially a work On the Good,from which we learn that Plato’s metaphysics is adialectical metaphysics,founded on an original opposition of two principles that shapes the whole reality—these principles being the One and the indefinite Dyad.Sensible things participate in ideas(they receive their being from ideas)and the intermediate mathematical entities lie between these two realities.However,ideas can be traced back to ideal numbers and the principles of ideal numbers are the One and the indefinite Dyad.Thus,these principles constitute their metaphysical foundation of ideas and,through the ideas,of the whole reality.

Natural Science and the Evolution of Categorial Discourse

In the second half of the last century the problem of categories became less and less prominent in philosophical debates. This twilight of categorial discourse did not go unnoticed, and some authors offered different solutions for the revival of categorial theorizing in contemporary philosophy＇s repertoire. One of these authors is the American philosopher Stephen Pepper. The purpose of the present discussion is to offer yet another explanation for the decline of categorial theory, and to explore Pepper＇s view and its role in the transformation of categorial discourse. The main thesis which I will argue for is that traditional categories did not disappear altogether, but they have been replaced, gradually, by key empirical concepts from natural science. Even if such concepts do not satisfy the traditional requirements categories in shaping our for a categorial scheme, they are, nonetheless, fulfilling the same role as traditional worldviews.
