RESUMEN
Numerous studies have explored the connection between lumbar osteophytes, their pathophysiology, and instability since Macnab's 1971 report on traction spurs as an indicator of lumbar instability. This study provides a narrative historical overview of traction spurs, a classic finding that suggests lumbar instability. It summarizes the causes of anterior lumbar vertebral osteophytes, the relationship between traction spurs and lumbar spinal instability, and the clinical significance of traction spurs. Vertebral osteophytes are grouped into two categories, namely, traction spurs or claw spurs, which represent different stages of the same pathological process. Traction spurs are indicative of instability and occur in the early stage of disc degeneration, characterized by temporary dysfunction or instability. Traction spur formation following fusion surgery can predict union or nonunion, and it serves as an indicator of preoperative and postoperative segmental instability. The relationship between traction spurs and radiographic instability, as well as their association with imaging findings such as CT and MRI, has been clarified. Additionally, finite element analysis and mechanical testing have been used to investigate the significance of traction spurs. However, further research is needed to verify that traction spurs are an accurate indicator of pre- and postoperative lumbar instability.
RESUMEN
In the first issue of Graefe's Archive from 1854, Albrecht von Graefe wrote about glaucoma. Glaucoma comes from the Greek word "glaukos," gleaming, which was first used by Homer around 800 BCE. Since then, glaukos and glaucoma have taken on many different meanings. The terms blindness, cataract and glaucoma were used interchangeably and twisted together in incomprehensible contexts. Over 2500 years of glaucoma theories were upset by the discovery of the ophthalmoscope in 1851. The first reports of increased intraocular pressure appeared in the mid-seventeenth century, but it took over 200 years for this elevated pressure to be accepted by the ophthalmological community. The discovery of glaucoma simplex in 1861 was an important step forward. What did doctors know about glaucoma before 1850 and why did it take so long to classify glaucoma in its various categories? And why is it that we still do not know what the cause is for primary open angle glaucoma? I will try to answer some of these questions after a historical overview.

The drivers of the HIV epidemic, the viruses, the opportunistic infections, the attitudes and the resources allocated to the fight against HIV/AIDS, vary substantially across countries. French Guiana, at the crossroads between Amazonian South America and the Caribbean, constitutes a singular context with poor populations and rich country health funding, which has allowed researchers to gather lots of information on the particulars of our epidemic. We aimed to focus on the little known story of forty years of HIV research in French Guiana and emphasize how local research intertwined with public health action has yielded continuous progress, despite the difficult social conditions of the affected population. We searched Web of Science and associated local experts who worked through much of the epidemic in selecting the most meaningful products of local research for clinical and public health outcomes in French Guiana. Research tools and facilities included, from 1991 onwards, the HIV hospital cohort and the HIV-histoplasmosis cohort. Ad hoc studies funded by the ANRS or the European Regional Development fund shed light on vulnerable groups. The cumulative impact of prospective routine collection and focused efforts has yielded a breadth of knowledge, allowing for informed decisions and the adaptation of prevention, testing and care in French Guiana. After this overview, we emphasize that the close integration of research and public health was crucial in adapting interventions to the singular context of French Guiana.
RESUMEN
We describe developments in understanding of the porphyrias associated with each step in the haem biosynthesis pathway and the role of individuals whose contributions led to major advances over the past 150 years. The first case of erythropoietic porphyria was reported in 1870, and the first with acute porphyria in 1889. Photosensitisation by porphyrin was confirmed by Meyer-Betz, who self-injected haematoporphyrin. Günther classified porphyrias into haematoporphyria acuta, acuta toxica, congenita and chronica. This was revised by Waldenström into porphyria congenita, acuta and cutanea tarda, with the latter describing those with late-onset skin lesions. Waldenström was the first to recognise porphobilinogen's association with acute porphyria, although its structure was not solved until 1953. Hans Fischer was awarded the Nobel prize in 1930 for solving the structure of porphyrins and the synthesis of haemin. After 1945, research by several groups elucidated the pathway of haem biosynthesis and its negative feedback regulation by haem. By 1961, following the work of Watson, Schmid, Rimington, Goldberg, Dean, Magnus and others, aided by the availability of modern techniques of porphyrin separation, six of the porphyrias were identified and classified as erythropoietic or hepatic. The seventh, 5-aminolaevulinate dehydratase deficiency porphyria, was described by Doss in 1979. The discovery of increased hepatic 5-aminolaevulinate synthase activity in acute porphyria led to development of haematin as a treatment for acute attacks. By 2000, all the haem biosynthesis genes were cloned, sequenced and assigned to chromosomes and disease-specific mutations identified in all inherited porphyrias. These advances have allowed definitive family studies and development of new treatments.
RESUMEN
Infectious diseases are the common enemies of mankind. In the course of historical development, they persistently threaten human health and safety. Even today, despite the developments in medical science, we cannot escape the fear and suffering caused by infectious diseases. Whether in ancient or modern times, the source of infection, route of transmission, and a susceptible population are the three key conditions for the prevalence and spread of infectious diseases. All factors closely related to these three conditions can affect the prevalence of infectious diseases. China is one of the cradles of world civilization. The ancient people accumulated a great deal of experience and lessons in the long struggle against infectious diseases. In the face of the current threat posed by widespread infectious disease, it is imperative to review and summarize ancient Chinese ideas and health policies on epidemic prevention and control to inspire contemporary efforts in the prevention and control of infectious disease. The combination of prevention-oriented epidemic prevention ideology and traditional medicine provides valuable insights, especially for impoverished and medically underserved regions.

While both Crohn' disease (CD) and ulcerative colitis (UC) are known to predispose patients to certain intestinal malignancies, the exact mechanism of carcinogenesis remains unknown and optimal screening guidelines have not been established. This article will explore the history of our understanding of intestinal malignancy in inflammatory bowel disease (IBD). To contextualize the medical community's difficulty in linking each condition to cancer, the first section will review the discovery of CD and UC. Next, we discuss early attempts to define IBD's relationship with small bowel adenocarcinoma and colorectal cancer. The article concludes with a review of each disease's surgical history and the ways in which certain procedures produced poor oncologic outcomes.

BACKGROUND: Practically every facet of the most common odontogenic tumor, odontoma, has been covered by an extensive volume of literature. However, uncertainty about its precise history has persisted. MATERIALS AND METHODS: The historical evolution of odontoma was traced with reference to the original illustrations that accompanied European and American reports published at the beginning of the 19th century and also at the turn of the century. RESULTS: The prevailing views regarding the first description of odontoma by Oudet of Paris in 1809 and the original designation "odontome" by Broca of Paris in 1867 are not entirely accurate. Before Broca's suggested term, "exostose dentaire" (dental exostosis) and "tumeur dentaire" (dental tumor) proposed by Oudet and Forget of Paris, respectively, were popular terms adopted in France, while in Briatin the terms "warty tooth" and "supernumerary teeth" proposed by Salter and Tomes of London, respectively, were widely coined. The original illustrations of complex odontoma were published by Wedl of Vienna in 1851, and in 1862 Tomes published the first drawing of compound odontoma denticles. Before the advent of diagnostic radiography in the early 1900s, spontaneous exposure or eruption of odontoma followed by secondary infection was very common. In 1887-1888, Bland Sutton of London criticized Broca's monumental research and formulated the first modern classification which, in essence, remains valid today. At that time, large osteomas of the maxilla were inappropriately classified as odontomas by many pathologists because of Bland Sutton's influential view. Interestingly, the first radiographic evidence of odontoma was published by the American oral surgeon Gilmer in 1899. CONCLUSION: In view of their fundamental achievements, the names of Wedl, Salter, Broca and Bland Sutton have been closely associated with the true history of odontoma.

Sleep helps to consolidate previously acquired memories. Whether new information such as languages and other useful skills can also be learned during sleep has been debated for over a century, however, the sporadic studies' different objectives and varied methodologies make it difficult to draw definitive conclusions. This review provides a comprehensive overview of the history of sleep learning research conducted in humans, from its empirical beginnings in the 1940s to the present day. Synthesizing the findings from 51 research papers, we show that several studies support the notion that simpler forms of learning, such as habituation and conditioning, are possible during sleep. In contrast, the findings for more complex, applied learning (e.g., learning a new language during sleep) are more divergent. While there is often an indication of processing and learning during sleep when looking at neural markers, behavioral evidence for the transfer of new knowledge to wake remains inconclusive. We close by critically examining the limitations and assumptions that have contributed to the discrepancies in the literature and highlight promising new directions in the field.

Collaborative learning and cooperative learning are two separate approaches developed independently by two groups of scholars around the same period of time in the 1960 and 1970 s. Due to their different origins and intertwined paths of development, they have their own distinct features while sharing many similarities. The relationship between collaborative learning and cooperative learning can be confusing. Therefore, this paper provides a brief historical review of collaborative learning and cooperative learning to identify the origins of each, where they diverge from each other, and where they are aligned. This paper examines the definitions of the two terms and compares their characteristics. This is followed by a discussion of their historical development in the last fifty years: early development between the 1960 and 1970 s; maturation in the 1980 and 1990 s; convergence in the mid-1990s; and the emergence of Computer-Supported Collaborative Learning (CSCL) in the late 1980s. Finally, this paper summarizes the four paradigms of mainstream research on collaborative and cooperative learning, namely, the "effect" paradigm, the "conditions" paradigm, the "interaction" paradigm, and the "design" paradigm.
RESUMEN
Health poverty alleviation is an effective tool for improving the living quality and developmental conditions of impoverished populations. Since 1978, China has been actively implementing health poverty alleviation projects, resulting in a more robust rural healthcare service network and increased convenience for the local population to access medical treatment. However, it is crucial to acknowledge that China still faces a complex situation with the simultaneous existence of multiple disease threats and the interweaving of various health influencing factors. Ongoing risks of emerging infectious diseases persist, and some previously controlled or eliminated infectious diseases are at risk of resurgence. The incidence of chronic diseases is on the rise and exhibits a trend toward affecting younger populations. Therefore, examining the successful experiences of China's health poverty alleviation over the past 40 years becomes a critically important issue. The study focuses on China's health poverty alleviation policies, employing historical institutionalism as a theoretical perspective to analyze the historical changes and evolutionary logic of health poverty alleviation policies. A historical institutionalist analytical framework for health poverty alleviation policies is constructed. The research findings reveal that China's health poverty alleviation policy has undergone three distinct periods since 1978: the initial phase (1978-2000), the exploratory phase (2000-2012), and the stable development phase (2013-present). At the macro level, the political, economic, and social contexts of different periods have influenced the evolution of health poverty alleviation policies. On the meso level, coordination effects and adaptive expectations have had an impact on China's health poverty alleviation policy. At the micro level, various actors, including the central government, local governments at different levels, social forces, and impoverished communities, interact during the evolution of health poverty alleviation policies. This paper summarizes the theoretical aspects of China's health poverty alleviation policy experience. The research conclusions, viewed through the lens of historical institutionalism, offer practical insights into the evolution of government policies. This provides directional guidance for enhancing health poverty alleviation projects.

The government performance appraisal of public hospitals serves as an effective management tool to promote high-quality development. It is also an important means of realizing the "Healthy China" initiative. Since the founding of the People's Republic of China, changes in performance appraisal have been divided into the following four periods: the early stage of performance appraisal (1949-1977), the exploration period (1978-2008), the development period (2009-2018), and the integration period (2019-present). This clarifies the regional practice of public hospital performance and identifies the institutional factors of the evolution. It also demonstrates that administrative forces, market-driving forces, and mission-driving forces combine to bring about change in the public hospital performance appraisal system. However, problems such as insufficient application of performance appraisal and coordination between health administrative departments and medical insurance departments still loom large.

The nasopharynx has been understudied relative to neighboring anatomical regions. It is a highly complex, integrated space whose function, development, and evolution remains unclear after nearly 5,000 years of study. Historically, most work on the nasopharynx was done with a focus on adjacent structures. It has most often been mentioned in relation to the middle ear (via the Eustachian tube) in ancient texts and has only later been given a designation as one of three portions of a tripartite pharynx among adult humans. As human dissection became practiced more widely in Renaissance Europe, understanding of the nasopharyngeal boundaries improved. With further advancements in the study of nasopharyngeal development, evolution, and anatomical variation from the 19th century up until the present, this region has been shown to be functionally vital and still complicated to define.

Androgen deprivation therapy (ADT) has been the main management strategy for prostate cancer for more than eight decades, nowadays achieved commonly by administration of luteinizing hormone-releasing hormone agonists. ADT markedly suppresses androgen hormones with the long-term risks of adverse events such as muscle weakness, impairment of glucose and lipid metabolism, impotence, osteoporosis, and secondary fractures. Extensive research has provided significantly better insight into the dynamics of ADT including identification of the benefits of sequential and combination therapies. This has led to the development of new pharmaceutical ADT modalities. This review provides a general overview of the evolution of ADT in the context of the new emerging pharmaceutical ADT modalities so that clinicians and medical providers have a better understanding of personalizing the available ADT options with their different risk-benefit profiles.
