Abulcasis (936-1013): his work and contribution to orthopaedics.

AIM OF THE STUDY: The purpose of this historic review is to summarize the life and work of Abulcasis (936-1013) and his contribution to surgery and orthopaedics. METHOD: We conducted an extensive search in libraries as well as online in PubMed and Google Scholar. RESULTS: Abulcasis in his work combines the knowledge of ancient Greek and Roman physicians and surgeons with the extensive knowledge of Arabic medicine and pharmacology. He also pioneered surgical technique with the invention of numerous surgical instruments and with several revolutionary surgical techniques. CONCLUSION: Abulcasis made an impact with his medical writings in which he summarized the works of ancient Greek and Roman physicians like Hippocrates and Galen with the influence of medieval authors and the knowledge of the Arabic medicine and pharmacology. His descriptions and innovations in his work remained a work of reference in the West and East for many centuries to come.

[MUSCULOSKELETAL MARKERS, ARTHROPATY, TRAUMAS]. / INDICATORI SCHELETRICI DI LAVORO: MARCATORI MUSCOLO-SCHELETRICI, ARTROPATIE E TRAUMI.

The bone tissue remodeling due to strong physical/working activity is defined as ergonomic markers or MSM (Muscoloskeletal Stress Markers) (Capasso et al. 1999) and MOS (Markers of Occupational Stress). Among them we can find: enthesopaties, arthropaties, non metrical stress and traumas markers. In the present study, the analysis of these traits has been used to clarify habitual activity patterns of four imperial populations from Suburbium: Castel Malnome, Casal Bertone area Q, Via Padre Semeria e Quarto Cappello del Prete. The very high prevalence of activity-induced stress lesions occurred among the individuals of Castel Malnome and Casal Bertone area Q suggests that these groups were involved in strenuous occupations such as, respectively: the processing and storage of salt and the dyeing of textiles and hides discernible from the archaeological context. For the individuals of Via Padre Semeria and Quarto Cappello del Prete the alterations, instead, could be compatibles with agricultural work.

A legacy of struggle: the OSHA ergonomics standard and beyond, Part I.

In November 2000, the Occupational Safety and Health Administration (OSHA) issued an ergonomics standard to prevent debilitating work-related musculoskeletal disorders (WMSDs). It was rescinded by Congress within four months. We explore how this story unfolded over two decades of collaboration and conflict. Part I provides an overview of the historical context of the struggle for a standard, followed by interviews with key players from labor, academia and government. They provide a snapshot of the standard; discuss the prevalence of WMSDs in the context of changing work organization; give insight into the role of unions and of scientific debate within the context of rulemaking; and uncover the basis for the groundbreaking OSHA citations that laid the foundation for a standard. Part II interviews further explore the anti-regulatory political landscape of the 1990s that led to repeal of the standard, discuss the impact of the struggle beyond the standard, and describe creative approaches for the future.

The 'scientific artworks' of Doctor Paul Richer.

This article examines the little-known sculptures of pathology created by Doctor Paul Richer (1849-1933) in the 1890s for the so-called Musée Charcot at the Hôpital de la Salpêtrière in Paris. Under the direction of Doctor Jean-Martin Charcot (1825-1893), one of the founders of modern neurology, Richer was the head of the hospital's museum of pathological anatomy, as well as the Salpêtrière's resident artist. His 'series of figural representations of the principal types of nervous pathology' included busts of patients suffering from labio-glosso-laryngeal paralysis and myopathy, as well as sculptures depicting patients with Parkinson's disease and juvenile hypothyroidism. These patient portraits were seen as objective, while also paradoxically providing an alternative to mechanical media, such as the photograph and the cast, by permitting the doctor's intervention in not only controlling and animating the sitter, but also emphasising the patient's symptoms. This was a new kind of medical specimen: the 'scientific artwork', as they were called by a contemporary. This phrase, far from being an oxymoron, indicates the purposive collapse of the objective ('scientific') and subjective ('artistic') binary in Richer's sculptures of pathology. Through a detailed examination of three of Richer's works, this article problematises the categories traditionally used to describe, analyse and understand medical imagery and complicates our understanding of the relationship between science and art at the end of the nineteenth century.

The discipline of ergonomics in Cuba within the occupational health framework: background and trends.

The concept of ergonomics was introduced in Cuba at the beginning of the 1970s. More than 40 years later, the prevailing approach to workers' health is still generally reactive rather than proactive, despite the commitment of the government to the subject. A factor influencing this issue is, generally, lack of recognition of the benefits of establishing ergonomic principles within most occupational activities. Recent progress to move occupational health practice toward a more preventive approach has been conducted, frequently with international support. The introduction of a set of Cuban standards proposing the necessity of ergonomic evaluations is an example of this progress. The main challenge for Cuban ergonomists is to transfer knowledge to occupational health practitioners in order to be in concordance with basic standards and regulations regarding ergonomics. The article offers a short description of the history of ergonomics and an overview of ergonomics practice in Cuba.

Variation of musculoskeletal stress markers in the medieval population from Cedynia (Poland)--proposal of standardized scoring method application.

The objective of this paper is: (a) to present a rating scale for the evaluation of the musculoskeletal stress markers; (b) to analyze the medieval population from Cedynia in terms of the degree of expression and frequency of the musculoskeletal stress markers. The presented rating scale was developed based on the variability of the morphology of muscle attachment sites, observed in the skeletal material from Cedynia (102 males and 99 females). The scale encompasses 10 musculoskeletal stress markers located on the scapula, humerus, radius, femur and tibia. The system reflects three degrees (1, 2, 3) of complexity of the muscle attachment sites morphology. The analysis of asymmetry and sexual dimorphism of the musculoskeletal stress markers was made based on the chi2 (Pearson) statistics or chi2 statistics for 2 x 2 tables. Moderate degree (2) of muscle attachment site complexity is the most frequent degree of musculoskeletal stress markers development in the population from Cedynia. Low (1) and high (3) complexity of muscle attachment site are the most seldom observed categories. No statistically significant differences between the frequencies of the musculoskeletal stress markers on the bones of the right and left side of the skeleton were noted in females. Also in males the differences found were not statistically significant. Only in the case of deltoid tuberosity (H2) p = 0.052 oscillating around the threshold value may suggest existence of a statistically significant difference in the degree of expression of this stress marker on the bone of the right and left side of the skeleton. On the bones of the right side of the skeleton dimorphic differences were observed in the glenoid tuberosity (S2), bicipital groove (H1), pronator teres origin (R2), tibial tuberosity (T1), soleal crest (T2) and linea aspera (F2). On the bones of the left side of the skeleton dimorphic differences were noted for the bicipital groove (H1), pronator teres origin (R2) and glenoid tuberosity (S2).

Thomas L. DeLorme and the science of progressive resistance exercise.

In the latter years of the Second World War, the number of American servicemen who had sustained orthopedic injuries was overwhelming the nation's military hospitals. The backlog of patients was partly because of the sheer number of soldiers involved in the war effort, but it was exacerbated by rehabilitation protocols that required lengthy recovery times. In 1945, an army physician, Dr. Thomas L. DeLorme experimented with a new rehabilitation technique. DeLorme had used strength training to recover from a childhood illness and reasoned that such heavy training would prove beneficial for the injured servicemen. DeLorme's new protocol consisted of multiple sets of resistance exercises in which patients lifted their 10-repetition maximum. DeLorme refined the system by 1948 to include 3 progressively heavier sets of 10 repetitions, and he referred to the program as "Progressive Resistance Exercise." The high-intensity program was markedly more successful than older protocols and was quickly adopted as the standard in both military and civilian physical therapy programs. In 1951, DeLorme published the text Progressive Resistance Exercise: Technic and Medical Application, which was widely read by other physicians and medical professionals. The book, and DeLorme's academic publications on progressive resistance exercise, helped legitimize strength training and played a key role in laying the foundation for the science of resistance exercise.

Concepts of orthopedic disorders in Avicenna's Canon of Medicine.

This manuscript offers a brief review of the orthopedic subjects in the Canon of Medicine. Highlights include, but are not limited to, the anatomy of the musculoskeletal system, fractures and dislocations, nerve and tendon injuries, different types of wounds and ulcers, and bone infections. Some of the concepts regarding musculoskeletal disorders remain relevant to current orthopedic knowledge. Reviewing the orthopedic subjects in the Canon of Medicine reveals that Avicenna has made a significant contribution to the evolution of orthopedic knowledge.

Bernardino Ramazzini and the new epidemics of work-related disorders.

Work-related diseases (such as musculoskeletal disorders, neoplasms cardiocirculatory and psycho-social problems disorders) represent an increasing problem that countries are becoming aware of. In particular, musculoskeletal disorders, affecting workers in a variety of occupations, are a major cause of lost time from work and workers' disability. The paper reviews Ramazzini's observations of musculoskeletal disorders of subjects working in the second half of the seventeenth century. He observed that several clinical pictures were linked to a variety of factors (prolonged stationary postures, unnatural postures, repetition of movements, heavy muscular performance) and stressed the need to provide workforce with hygienic measures and information about hazards and preventive measures. It is worthy to stress that Ramazzini's observations, based on original intuitions and critical reasoning, anticipate the modern approach based on epidemiological principles.
