El obrero recuperado: medicina del trabajo, ortopedia y tecnología médica en la imagen social de las personas con discapacidades (Espa?a, 1922-1936)
Martínez-Pérez, José;
História, Ciências, Saúde-Manguinhos , 2006, DOI: 10.1590/S0104-59702006000200009
Abstract: the article explores how the development of medical technologies helps to change our social perception of people with disabilities. it analyzes the case of a program meant to attenuate the problems caused by work accidents, introduced at madrid's instituto de reeducación profesional de inválidos del trabajo in the 1920s. the specific focus is on the program's initiative in the arena of traumatology and orthopedics, aimed at the rehabilitation of disabled workers. the text underscores how these efforts helped to strengthen an "individual model" of disability and to shape the image conveyed to society about what could be expected of a person with certain physical disabilities.
Toxina botulínica y su empleo en la patología oral y maxilofacial
Martínez-Pérez,D.;
Revista Espa?ola de Cirugía Oral y Maxilofacial , 2004, DOI: 10.4321/S1130-05582004000300001
Abstract: abstract: botilinum toxins are exotoxins of the bacteria that form the clostridium botulinum spores and the causative agents of botulism. when injected into the muscle flaccid paralysis is produced. the clinical effect is directly related with the dose and is should be adjusted for each particular case. over the last twenty years that it has been in use, the botulinum toxin has shown itself to be a reliable drug. current indications for the use of botulinum toxin include all those pathologies which are the results of muscle hyperfunction and autonomic dysfunction.

Toxina botulínica y su empleo en la patología oral y maxilofacial Botulinum toxin and its use in oral and maxillofacial pathology
D. Martínez-Pérez
Revista Espa?ola de Cirugía Oral y Maxilofacial , 2004,
Abstract: Resumen: Las toxinas botulínicas son exotoxinas de la bacteria formadora de esporas Clostridim botulinum y los agentes causantes del botulismo. Cuando se inyecta en el músculo produce una parálisis flácida. El efecto clínico está directamente relacionado con la dosis y debe ajustarse para cada caso concreto. La Toxina botulínica ha demostrado en los más de veinte a os en que se está utilizando que es un fármaco seguro. Las indicaciones de la toxina botulínica en la actualidad incluyen todas aquellas patologías que resultan de la hiperfunción muscular y la disfunción autonómica.

Catalogando la diversidad del comportamiento humano: la nosología francesa decimonónica ante las conductas delictivas (1800-1855)
Martínez-Pérez, José
Asclepio : Revista de Historia de la Medicina y de la Ciencia , 1996,
Abstract: This work aims to contribute to the study of the factors which influenced the process of the classification of the diversity of human behaviour. As a result this study will look at the changes in operation at the beginning of the nineteenth century regarding the classification of one type of deviant behaviour: homicide. The creation by French psychiatrists of the diagnostic category "monomanie homicide instintive" meant that certain types of homicide were no longer considered a crime and began to be regarded as forms of madness. The emergence and gradual disappearance of this morbid species of psychiatric classifications in the first half of the XIXth century illustrates how the assignation of aberrant behaviour to one kind or other of deviance depends on the way in which various factors are related: changes in scientific theories, permutations in the professional objectives of those who make the classifications, and the degree of social consensus which is achieved for the new meaning that the deviatory behaviour acquires on changing its position among the various forms of deviation. El presente trabajo tiene como objetivo contribuir al conocimiento de los factores que influyen sobre el proceso de clasificación de la diversidad del comportamiento humano. Se estudia para ello los cambios operados a comienzos del siglo XIX en el modo de catalogar una forma de conducta desviada: la homicida. La creación por los psiquiatras franceses de la categoría diagnóstica de la monomanía homicida instintiva sirvió para que ciertos tipos de homicidios dejaran de ser interpretados como delitos y empezaran a ser contemplados como formas de locura. El surgimiento y progresiva desaparición de esta especie morbosa de las clasificaciones psiquiátricas de la primera mitad del siglo XIX pone de relieve cómo la asignación de un comportamiento aberrante a un tipo u otro de desviación depende de la manera en que se relacionan diversos factores: los cambios en las teorías científicas; las permutas en los objetivos profesionales de quienes hacen las clasificaciones; y el grado de consenso social que se consigue alcanzar para el nuevo significado que adquiere la conducta desviada al cambiar su ubicación entre las diversas formas de desviación.
Consolidating the medical model of disability: on poliomyelitis and the constitution of orthopedic surgery and orthopaedics as a speciality in Spain (1930-1950)
Martínez-Pérez, José
Asclepio : Revista de Historia de la Medicina y de la Ciencia , 2009,
Abstract: At the beginning of the 1930s, various factors made it necessary to transform one of the institutions which was renowned for its work regarding the social reinsertion of the disabled, that is, the Instituto de Reeducación Profesional de Inválidos del Trabajo (Institute for Occupational Retraining of Invalids of Work). The economic crisis of 1929 and the legislative reform aimed at regulating occupational accidents highlighted the failings of this institution to fulfil its objectives. After a time of uncertainty, the centre was renamed the Instituto Nacional de Reeducación de Inválidos (National Institute for Retraining of Invalids). This was done to take advantage of its work in championing the recovery of all people with disabilities. This work aims to study the role played in this process by the poliomyelitis epidemics in Spain at this time. It aims to highlight how this disease justified the need to continue the work of a group of professionals and how it helped to reorient the previous programme to re-educate the invalids . Thus we shall see the way in which, from 1930 to 1950, a specific medical technology helped to consolidate an individual model of disability and how a certain cultural stereotype of those affected developed as a result. Lastly, this work discusses the way in which all this took place in the midst of a process of professional development of orthopaedic surgeons. A comienzos de la década de 1930, una serie de factores obligaron a transformar una de las instituciones que más se había destacado en Espa a en la labor de conseguir la reinserción social de las personas con discapacidades: el Instituto de Reeducación de Inválidos del Trabajo. La crisis económica de 1929 y las reformas legislativas destinadas a regular los accidentes del trabajo pusieron de relieve, entre otros factores, las limitaciones de esa institución para cumplir sus objetivos. Tras un período de cierta indefinición, el centro reabrió sus puertas como Instituto Nacional de Reeducación de Inválidos. Se trataba así de aprovechar el impulso anterior para destinar sus actividades a la recuperación de todas las personas con discapacidades. El trabajo que presento intenta explorar el papel desempe ado en ese proceso por la presencia de la poliomielitis en esos a os en Espa a. Se pretende poner de manifiesto cómo esa enfermedad permitió justificar la necesidad de dar continuidad a la labor de un grupo de profesionales, y sirvió para reorientar el programa de reeducación de inválidos que se había implementado con anterioridad. A través de ello, es posible apreciar la m
Real valued functions and metric spaces quasi-isometric to trees
álvaro Martínez-Pérez
Mathematics , 2011,
Abstract: We prove that if X is a complete geodesic metric space with uniformly generated first homology group and $f: X\to R$ is metrically proper on the connected components and bornologous, then X is quasi-isometric to a tree. Using this and adapting the definition of hyperbolic approximation we obtain an intrinsic sufficent condition for a metric space to be PQ-symmetric to an ultrametric space.
Quasi-isometries between visual hyperbolic spaces

Mathematics , 2008,
Abstract: We prove that a PQ-symmetric homeomorphism between two complete metric spaces can be extended to a quasi-isometry between their hyperbolic approximations. This result is used to prove that two visual Gromov hyperbolic spaces are quasi-isometric if and only if there is a PQ-symmetric homeomorphism between their boundaries.

Abstract: We use Bieri-Strebel invariants to determine when a normal fibre product in the product of two finitely presented groups is finitely presented. We give conditions that imply and in some cases characterize the existence of such finitely presented fibre products.
Zig-zag chains and metric equivalences between ultrametric spaces
álvaro Martínez-Pérez
Mathematics , 2009,
Abstract: We study the classification of ultrametric spaces based on their small scale geometry (uniform homeomorphism), large scale geometry (coarse equivalence) and both (all scale uniform equivalences). We prove that these equivalences can be characterized with parallel constructions using a combinatoric tool called common zig-zag chain.
