Guidance parentale et respect de l'intimité. Deuil et érotisme chez les mineurs

Des parents semblent ignorer la limite entre ce que l'on est en droit de montrer et ce que l'on doit traiter avec pudeur. Une sorte d'ambiguïté les amène à être négligents et par là à tolérer des comportements ou des propos grivois de leurs enfants ou à en rire. Les thérapeutes sont invités à entreprendre un travail pédagogique de guidance parentale quand les frontières de l'intime sont floues et quand la confusion touche les jeunes devenant vulnérables et symptomatiques. Les auteurs exposent un cas d'anorexie chez une adolescente, dont la souffrance se trouve masquée par une série de comportements désinhibés. La surexcitation qui en découle peut apparaître comme une solution défensive pour lutter contre la dépression liée à l'expérience de séparation et de deuil. Pour favoriser la construction de représentations des territoires de l'intime plus respectueuses de la vulnérabilité des adolescents, les auteurs ont aussi proposé la sculpture familiale.Parental guidance and respect of intimacy. Young people's mourning and erotism. - Parents seem to be unaware of the borderline between what one may show and what one should handle with reserve. A kind of ambiguity drive them to be careless. As a result, they put up with suggestive behaviour or language from their children and even laugh at it. The therapists are invited to undertake an educational work of parental guidance when the boderlines of the intimate are hazy and when the confusion is affecting young people who become vulnerable and symptomatic. The authors present an anorexia case of a teenager whose distress is concealed by a series of uninhibited behaviours. The ensuing overexcitement could seem to be a defensive solution to fight against the depression related to parting and mourning experience. To encourage the building of representations of the territories of the intimate which would be more respectful of the teenagers vulnerability, the authors also suggest the technique of family sculpture.

Pin guidance of reconstruction plate contour: an expanded role of external fixation

This article presents a modification of intraoperative external fixation for mandibular reconstruction with free tissue flaps. This technique is indicated when preregistration of the reconstruction plate is not possible due to transmandibular tumor extension. Once standard external fixation has been carried out and prior to segmental mandibulectomy, additional pins are fixed to the connecting rod that delineate the mandibular contour in three-dimensional (3D) space. Following mandibulectomy, these pins allow accurate contouring of the reconstruction plate and improved restoration of mandibular contour, projection, and dental occlusion. A step-by-step description of the technique using models and intraoperative photos is presented. This method of mandibular reconstruction is a simple and time-effective alternative to intraoperative computer navigation and 3D modeling in select cases of oral carcinoma where tumor infiltration of the outer mandibular cortex precludes prebending of the reconstruction plates.

Análise genética de escores de avaliação visual de bovinos com modelos bayesianos de limiar e linear

O objetivo deste trabalho foi comparar as estimativas de parâmetros genéticos obtidas em análises bayesianas uni-característica e bi-característica, em modelo animal linear e de limiar, considerando-se as características categóricas morfológicas de bovinos da raça Nelore. Os dados de musculosidade, estrutura física e conformação foram obtidos entre 2000 e 2005, em 3.864 animais de 13 fazendas participantes do Programa Nelore Brasil. Foram realizadas análises bayesianas uni e bi-características, em modelos de limiar e linear. De modo geral, os modelos de limiar e linear foram eficientes na estimação dos parâmetros genéticos para escores visuais em análises bayesianas uni-características. Nas análises bi-características, observou-se que: com utilização de dados contínuos e categóricos, o modelo de limiar proporcionou estimativas de correlação genética de maior magnitude do que aquelas do modelo linear; e com o uso de dados categóricos, as estimativas de herdabilidade foram semelhantes. A vantagem do modelo linear foi o menor tempo gasto no processamento das análises. Na avaliação genética de animais para escores visuais, o uso do modelo de limiar ou linear não influenciou a classificação dos animais, quanto aos valores genéticos preditos, o que indica que ambos os modelos podem ser utilizados em programas de melhoramento genético.

Visuospatial working memory deficits and visual pursuit impairments are not directly related in schizophrenia.

OBJECTIVE: Patients with schizophrenia show deficits in visuospatial working memory and visual pursuit processes. It is currently unclear, however, whether both impairments are related to a common neuropathological origin. The purpose of the present study was therefore to examine the possible relations between the encoding and the discrimination of dynamic visuospatial stimuli in schizophrenia. METHOD: Sixteen outpatients with schizophrenia and 16 control subjects were asked to encode complex disc displacements presented on a screen. After a delay, participants had to identify the previously presented disc trajectory from a choice of six static linear paths, among which were five incorrect paths. The precision of visual pursuit eye movements during the initial presentation of the dynamic stimulus was assessed. The fixations and scanning time in definite regions of the six paths presented during the discrimination phase were investigated. RESULTS: In comparison with controls, patients showed poorer task performance, reduced pursuit accuracy during incorrect trials and less time scanning the correct stimulus or the incorrect paths approximating its global structure. Patients also spent less time scanning the leftmost portion of the correct path even when making a correct choice. The accuracy of visual pursuit and head movements, however, was not correlated with task performance. CONCLUSIONS: The present study provides direct support for the hypothesis that active integration of visuospatial information within working memory is deficient in schizophrenia. In contrast, a general impairment of oculomotor mechanisms involved in smooth pursuit did not appear to be directly related to lower visuospatial working memory performance in schizophrenia.

Is tagging with visual implant elastomer a reliable technique for marking earthworms?

Visual implant elastomer (VIE) has recently been employed to investigate different aspects of earthworm ecology. However, a number of fundamental questions relating to the detection and positioning of the tag, its persistence and potential effects on earthworms remain unknown. Seven earthworm species belonging to three ecological groupings, with different pigmentation and burrowing behaviour, were tagged using different coloured VIE. External inspection after two days, one week and 1, 10 and 27 months were followed by preservation, dissection and internal inspection. Tags could be seen in living specimens to 27 months, and dissection revealed that in most cases they were lodged in the coelomic cavity, held in place by septa. However, over longer time periods (more than two years), the chlorogogenous tissue tended to bind to the tags and made external observation increasingly difficult. Migration of the VIE material towards the posterior of the earthworm and potential loss of the tag were only observed on rare occasions, and a recovery rate in excess of 98% was recorded. By introducing a reasonable amount of VIE into segments, just after the clitellum, this technique can become a valuable tool in earthworm ecology and life history studies, particularly in short-medium term laboratory and field experiments.

Postictal cortical visual impairment: A symptom of posterior reversible encephalopathy.

We describe a patient presenting with a first generalized convulsion after alcohol consumption, in whom the early postictal finding of a rapidly regressive cortical visual impairment suggested the presence of a posterior reversible encephalopathy. This was confirmed radiologically, and probably represented the key factor in the seizure etiology.

07020-007 Hurley Creek Watershed/McKinley Lake Final Report

The Hurley Creek Watershed is a micro-watershed of approximately 2,211 acres (3.5 square miles), which drains into the Platte River southwest of Creston. The watershed is 64% urban and 36% rural. The urban area includes the bulk of the town of Creston (population 7,597) and the rural area is just north of Creston, which includes the origin of Hurley Creek. Hurley Creek Watershed was examined for improvements following a citizens group in 2004 determined a need and desire to make McKinley Lake, a 65-acre city-owned lake, a quality fishery and viable swimming lake, as it once was. As part of a major park improvement project over ten-plus years, the watershed improvement project is undertaken to reduce pollution entering the lake. In 2006, IOWATER volunteers, under guidance of the town’s consultants, sampled the stream in 8 locations throughout the year, a total of 92 samples. The samples, along with visual inspections of the creek, found three major impairments: 1) high E. Coli levels, 2) severe erosion, and 3) storm water management. Using the Watershed Project Planning Protocol, the consultant and a volunteer committee of interested citizens determined that five physical and three administrative actions should be undertaken. The request will help: identify sources of E. Coli and reduce its delivery into the watershed, control animal access, manage storm water, implement stream-bank stabilization, educate the public, and develop miscellaneous small projects on specific properties.

Bilateral transitory projection to visual areas from auditory cortex in kittens.

A transitory projection from primary and secondary auditory areas to the contralateral and ipsilateral areas 17 and 18 exists in newborn kittens. Distinct neuronal populations project to ipsilateral areas 17-18, contralateral areas 17-18 and contralateral auditory cortex; they are at different depth in layers II, III, and IV. By postnatal day 38 the auditory to visual projections have been lost, apparently by elimination of axons rather than by neuronal death. While it was previously reported that the elimination of transitory axons is responsible for focusing the origin of callosal connections to restricted portions of sensory areas it now appears that similar events play a more general role in the organization of cortico-cortical networks. Indeed, the elimination of juvenile projections is largely responsible for determining which areas will be connected in the adult.

Visual realism enhances realistic response in an immersive virtual environment

Participants in an immersive virtual environment interact with the scene from an egocentric point of view that is, where there bodies appear to be located rather than from outside as if looking through a window. People interact through normal body movements, such as head-turning,reaching, and bending, and within the tracking limitations move through the environment or effect changes within it in natural ways.
