The author analysesEncyclopédie’s articles devoted to nervous and mental functioning and disorders, showing that a new approach to lunacy as a mental illness, which is defined in some articles as a “general trouble of the animal economy”, progressively emerged. The term,animal economy, unified physical and moral aspects of the study of man. It was elaborated by XVIIIth century physiologists and was widely accepted by French physicians. This idea is based on the vitalistic thought of the Montpellier school, which equated life with sensibility, and on English medical conceptions of a nervous-centred organism. Later on Philippe Pinel’s work displayed the legacy of these conceptions. On one hand, the comprehensive view of physical and moral dimensions in theanimal economy neutralized the question of an organic or psychogenetic origin of madness. This enabled him to consider it as a determinate field of sensibility interactions and as a medical matter, and to legitimize the group of therapeutic practices that he namedtraitement moral. On the other hand, Pinel departed from the classical conception ofanimal economy by developing his concept of aprinciple of mania, which underlies the manifold symptoms and forms of madness, and which are only perceptible to a trained specialist (aliéniste). The historical development analysed in this article show how alienists were enabled to claim both the wholly medical nature of insanity as disease, and their specific competence as apart from the other medical disciplines. To this extent, Esquirol achieved Pinel’s scientific work. 相似文献

Peripheral mechanisms responsible for penile erection are dependant upon a complex control by the nervous system, including peripheral nervous pathways, spinally mediated reflex loops and supraspinal nervous structures. Spinal cord injury is accompanied by a partial or a complete modification of these controls. In relation to the reflexogenic or psychogenic origin of penile erection, spinal cord injury does not cause the same effects. Reflexogenic erections sitll occur after spinal cord injury at a suprasacral level. After lesions at a level lower than the thoracolumbar spinal cord, tumescence following psychogenic stimulation has been observed. The hypotheses resulting from clinical and experimental observations and explaining the differences at the origin of these response are detailed. The recent developments in the neurophysiology of penile erection and the role of neurotransmitters allow a more analytical approach of the phenomenous and also bring new insights into possible compensatory pathways following spinal cord injury. 相似文献

Summary Sandy clay loam soils in the La Roche-Posay area, and the different parts ofTrifolium repens growing on 9 locations, were analyzed for their contents of selenium and 16 other elements.
The level of K, P, Se in the young leaves was 2 or 3 times higher than in the old organs. The roots showed the lowest contents
for these three elements. By contrast, their content of Al, Fe, As were 10 times higher than in the young leaves.
When the content of Se in leaves and roots was low, the contents of P, Al and Fe increased with increasing contents of Se.
When the level of Se was high, the reverse was the case.

We argue that clinical psychiatry oscillates between two epistemological poles: inference and perception. The inferential approach categorises illnesses bottom up, from visible symptoms to the pathological category supposedly causing them. In doing so, psychiatry moves away from the possible instantaneous perception of a patient, as well as from illness as a changing, evolving, phenomenon. From a phenomenological point of view, the perceptive approach enables the therapist, within an encounter, to experience the emergence of an impression of a patient’s overall bearing, or attitude. Thanks to épochè, a sense of form, Gestalt will emerge. The clinical case, nevertheless, is always a construction, an intersubjective narrative about illness, recounted by the patient. Creating a library of clinical cases leads to the development of case types, each becoming a reference to which future clinical cases can be compared and categorised as belonging to a clinical family; it is the participant with respect to Plato’s eidos. Phenomenology contributes to clinical experience in that it makes possible the link between perception and inference, between subjective experience and intersubjective narrative, and between person and case type. 相似文献

Semen analysis is subject to great variability, partly due to the mechanism of ejaculation. This variability can be reduced by taking certain precautions, such as interviewing the patient to eliminate any external factor of variability, by imposing a 3- to 5-day period of sexual abstinence, by explaining the procedures to avoid bacterial contamination of the sample, by verifying whether the whole semen sample has been collected, by checking that the temperature of the sample is maintained at 37°C and finally, by carefully homogenising the sample to obtain good quality liquefaction. 相似文献

Massive scrotal lymphoedema with gross genital deformation is called penoscrotal elephantiasis. It is a rare syndrome outside of filariasis endemic regions. It is usually idiopathic and rarely congenital or secondary. It is both physically disabling and emotionally distressing for the patient. Surgical treatment is often necessary. The authors report a case of a patient with penoscrotal elephantiasis in whom no aetiology could be found. Complete surgical resection of the diseased tissue and scrotum and penile reconstruction were performed with good cosmetic and functional results. 相似文献

In the Sahara, wherever there are naked rock surfaces, engravings and paintings have been found in large numbers. This rock art includes various types of images — the oldest dating about ten millenniums — among which human beings, wild or domesticated animals, therianthrops and non-explicit images can be identified. According to periods and styles, the human being has been represented under extremely varied aspects from particularly realistic — similar to the reality — till very simplified, even caricatural drawings. For some realistic representations of women and men, we can observe anatomical or morphological peculiarities which, without being frequent, show cases of steatopygy and gynoïd or androïd obesity, pathological or not. For certain periods, we also find imaginary, fantastic or caricatural representations. These images characterize particularly styles previous to that called “Round Heads”. So, in the Saharan art, the human being has been represented either in his physical truth, or according to multiple stylistic conventions or graphic stereotypes, which could characterize certain ethnic groups. 相似文献

With the exception of disease or drug-induced changes in Leydig cell function, aging is accompanied by specific changes of androgen status in healthy men. The level of testosterone production decreases in contrast with the rise in plasma protein testosterone binding capacity. Free testosterone, considered to be the biologically active fraction, decreases, leading to tissue androgen deficiency. The resulting clinical picture mimics hypogonadism, including physical and psychological asthenia, decreased libido and sexual behaviour, increased fat mass and decreased lean mass, gynaecomastia, osteoporosis and pro-atherogenic metabolic changes. The cut-off value for plasma testosterone below which androgen deficiency can be considered to be responsible for clinical signs is a key point which determines the therapeutic approach. In the absence of clearly validated data in healthy aging males, this cut-off value has been consensually defined as the mean plasma testosterone levels of men between 30 and 50 years of age minus two standard deviations, corresponding to the zone of hypogonadism in adult males. The association of clinical signs compatible with hypogonadism and reduced total (or preferably bioavailable) plasma testosterone level justifies initiation of hormone replacement therapy after excluding any contraindications (especially prostatic). The aim of this treatment is to reverse the consequences of age-related hypogonadism. Some benefits of this treatment have been clearly demonstrated, such as a decrease of fat mass, and an increase of lean mass and muscle strength. Similarly, bone mineral density increases, particularly in men with the lowest pretreatment plasma testosterone levels. It must be stressed that these changes are observed in truly hypogonadal aging men, but not in aging men with normal plasma testosterone levels. Testosterone replacement therapy can promote the development of gynaecomastia, while dihydrotestosterone tends to reduce gynaecomastia. Finally, androgen replacement therapy appears to improve a hypogonadism-related decrease in libido or sexual behaviour, provided other associated non-endocrine factors have been previously treated. Androgen replacement therapy improves well-being, and physical and psychological asthenia in hypogonadal men. However, this treatment has not been demonstrated to be effective in healthy aging men. Although androgen replacement therapy does not have a negative impact on lipid parameters, its possible cardiovascular protective effects have not yet been demonstrated. In conclusion, androgen replacement therapy, respecting the contraindications, is beneficial in patients of all ages with clearly demonstrated hypogonadism, but has no efficacy on symptoms in other cases. 相似文献

In contrast with the abrupt cessation of ovarian function at menopause in women, alteration of testicular functions in aging males is partial and progressive. Several cross-sectional studies have demonstrated an age-related decrease of testosterone levels in men. This decrease has also been observed when only men in good health are included in such studies. This age-related decline of testosterone levels has been recently confirmed by a longitudinal study including a large number of subjects. The progressive decline begins early, from the late thirties, and continues at a constant rate throughout the subject’s lifetime. Since SHBG increases with age, free testosterone and non-SHBG-bound testosterone (referred to as bioavailable testosterone) decrease more markedly than total testosterone. As variations of SHBG levels (mainly a decrease in obese and/or insulin-resistant subjects) are often encountered in clinical practice and as it is difficult to reliably measure free testosterone, bioavailable testosterone appears to be the better index to diagnose androgen deficiency in the aging male. Elevation of basal LH levels, decrease of hCG-induced testosterone levels and reduction of Leydig cell number demonstrate the testicular origin of hypogonadism. However, gonadotropic function is also relatively altered with aging. As a result of this alteration of gonadotropic function, LH level is not a reliable index of hypogonadism in the aging male. None of the androgen-dependent functions that are altered with aging, i.e. libido, erectile function, sense of well-being, muscle mass, muscle strength, fat mass, bone mass, etc., are exclusively controlled by androgens. In clinical practice, the indication for androgen replacement therapy must therefore be based on a combination of clinical symptoms and a reduction of bioavailable testosterone below a certain cut-off value, indicating “significant” hypogonadism. 相似文献

Situated a few kilometres from Angles-sur-Anglin (Vienne, France), the Roc-aux-Sorciers cave has yielded in 1927 and 1950 industry of the Middle and Upper Magdalenian periods. Our analyses of the sedimentary filling, dated from isotope stage 2, demonstrate the existence of two climatic sequences in the six ensembles defined during the excavations. A first sequence, at the base of the cave filling, corresponds to the occupation levels of the Middle Magdalenian and of the early Upper Magdalenian. At that time, the climate was globally cold and particularly humid, a conclusion that does not support Bastin's 1975 hypothesis on the oscillation of Angles-sur-Anglin, which postulates a mild and humid climate. In fact, the climate evolved progressively towards a slight warming from the base to the top of the stratigraphy. During the second sequence, corresponding to the occupation period of the Upper Magdalenian, the relatively stable climate was slightly warmer and quite humid. Stratigraphical and sedimentological data thus provide new information on the conditions under which the filling was deposited and on the palaeoclimatology of the Poitou-Charentes region during Magdalenian occupation. 相似文献
