Approches exégétiques du Deutéronome. Brève histoire de la recherche sur le Deutéronome depuis Martin Noth.

Depuis la parution des Überlieferungsgeschitliche Studien de Martin Noth, le livre du Deutéronome joue un rôle central dans la discussion exégétique. L'A. cherche à faire le point sur le chemin parcouru depuis cinquante ans. Au niveau diachronique, aucun consensus n'apparaît sur les questions de la datation et des rédactions successives. Le modèle le plus performant semble être Deutéronome primitif sous Josias suivi à l'époque de l'exil de son insertion dans l'historiographie, puis de plusieurs retouches rédactionnelles. Au niveau théologique, les thèmes de la loi, de l'alliance, du pays, de l'exode et des pères en sont l'épine dorsale

Place de la laparoscopie dans le traitement du cancer de l'endomètre [Laparoscopy in the management of endometrial cancer]

Les récents progrès de la laparoscopie ont modifié l'approche chirurgicale des patientes atteintes d'un cancer de l'endomètre. Le centre Swissendos Fribourg en collaboration avec l'AGO (Groupe de travail pour la gynécologie oncologique) et l'AGE (Groupe de travail pour la gynécologie endoscopique) ont entrepris d'élaborer un consensus basé sur l'évidence pour la pratique de la laparoscopie dans le traitement du cancer de l'endomètre. L'objectif a été de définir une approche propre à la Suisse en fournissant aux praticiens une aide à la prise en charge. Recent advance in laparoscopy have changed the surgical approach of endometrial cancer patients. The Swissendos Center, Fribourg, in collaboration with AGO (Groupe de travail pour la gynécologie oncologique) and AGE (groupe de travail pour la gynécologie endoscopique) have established a consensus based on the available evidence for the use of laparoscopy in the management of patients with endometrial cancer The main objective was to define Swiss clinical practice guidelines appropriate to the country and consistent with the needs of the physicians.

The daily energy expenditure in stable chronic obstructive pulmonary disease.

Resting energy expenditure is frequently increased in chronic obstructive pulmonary disease (COPD), but it is unknown if this hypermetabolism holds true over 24 h. The aim of this study was to measure the actual 24-h energy expenditure (24-h EE) in patients with stable COPD. Energy expenditure was measured by indirect calorimetry, using a metabolic chamber for 24-h EE and a canopy for basal metabolic rate (BMR). Physical activity was detected in the chamber by a radar system, and its duration was quantified. Two groups matched for age and height were studied: 16 male ambulatory patients with stable COPD and 12 male normal subjects. Body weight was 92 +/- 12% of ideal body weight in the group with COPD and 108 +/- 11% in the control group (p = 0.01). BMR was 120 +/- 7% of predicted in the group with COPD and 108 +/- 12% in the control group (p < 0.01). However, 24-h EE was similar in the two groups, amounting to 1,935 +/- 259 kcal in patients with COPD and 2,046 +/- 253 kcal in the control group (NS). This corresponded to 145% and 137% of predicted BMR, and to 121% and 126% of measured BMR in patients with COPD and the control group, respectively (NS). Patients were allowed to pursue their usual treatment within the chamber, and a positive correlation existed between 24-h EE and the daily dose of inhaled beta 2-agonists (p < 0.03). During daytime, physical activity was lower in patients with COPD. This study shows that patients with stable COPD are characterized by a normal daily energy expenditure in controlled conditions in spite of an increased basal metabolic rate. They appear to save energy by reducing their spontaneous level of physical activity.

New vineyard cultivation practices create patchy ground vegetation, favouring Woodlarks

Intensive agriculture, in which detrimental farming practices lessen food abundance and/or reduce food accessibility for many animal species, has led to a widespread collapse of farmland biodiversity. Vineyards in central and southern Europe are intensively cultivated; though they may still harbour several rare plant and animal species, they remain little studied. Over the past decades, there has been a considerable reduction in the application of insecticides in wine production, with a progressive shift to biological control (integrated production) and, to a lesser extent, organic production. Spraying of herbicides has also diminished, which has led to more vegetation cover on the ground, although most vineyards remain bare, especially in southern Europe. The effects of these potentially positive environmental trends upon biodiversity remain mostly unknown as regards vertebrates. The Woodlark (Lullula arborea) is an endangered, short-distance migratory bird that forages and breeds on the ground. In southern Switzerland (Valais), it occurs mostly in vineyards. We used radiotracking and mixed effects logistic regression models to assess Woodlark response to modern vineyard farming practices, study factors driving foraging micro-habitat selection, and determine optimal habitat profile to inform management. The presence of ground vegetation cover was the main factor dictating the selection of foraging locations, with an optimum around 55% at the foraging patch scale. These conditions are met in integrated production vineyards, but only when grass is tolerated on part of the ground surface, which is the case on ca. 5% of the total Valais vineyard area. In contrast, conventionally managed vineyards covering a parts per thousand yen95% of the vineyard area are too bare because of systematic application of herbicides all over the ground, whilst the rare organic vineyards usually have a too-dense sward. The optimal mosaic with ca. 50% ground vegetation cover is currently achieved in integrated production vineyards where herbicide is applied every second row. In organic production, ca. 50% ground vegetation cover should be promoted, which requires regular mechanical removal of ground vegetation. These measures are likely to benefit general biodiversity in vineyards.

Syndrome de Cogan : à propos d'un cas et brève revue de la littérature [Cogan's Syndrome]

We report the case of a 20-year-old woman, with no medical history, who in a short period of time developed the association of a bilateral vestibulocochlear deficit and a nonsyphilitic interstitial keratitis, the usual clinical presentation of Cogan's syndrome. This rare disease was named after David Cogan, the ophthalmologist to whom we owe the description of the first series of cases. The precise aetiology of Cogan's syndrome has yet to be defined, but clinical and biological evidence point toward an immunopathological process. Some authors distinguish between a typical and an atypical form of Cogan's syndrome, the former being associated with interstitial keratitis, the latter with other forms of ocular involvement. The diagnosis of Cogan's syndrome is mainly a clinical one, the association of a bilateral vestibulocochlear deficit and a non-syphilitic keratitis being almost specific. Cogan's syndrome is frequently associated with general signs and cardiovascular, neurological, rheumathological and digestive involvement. Laboratory data usually show nonspecific inflammatory signs (elevation of the white cell count and of the erythrocyte sedimentation rate). The mortality of the disease is essentially determined by its cardiovascular involvement, mostly aortic insufficiency, which should therefore actively be sought for in every patient. It is useful to emphasise that the typical form of Cogan's syndrome carries a higher risk regarding the development of aortic insufficiency, whereas the atypical form is more often associated with a systemic vasculitis. Treatment is mandatory, based upon corticosteroids, and must sometimes be intensified by the administration of a steroid-sparing immunosuppressive drug. Although our patient perfectly met the diagnostic criteria of Cogan's syndrome, the vestibular symptoms preceded the visual complaints, the reverse temporal sequence being more often reported in the literature. Systemic signs and cardiovascular involvement are frequently seen in Cogan's syndrome, but were notably absent in our patient. Blood samples showed inflammatory signs, whereas both lumbar puncture and cerebral MRI were normal, which is the usual pattern encountered in Cogan's syndrome. Following the rapid initiation of immunosuppressive therapy (Prednisone), the visual symptoms due to the bilateral keratitis resolved in a matter of days, whereas the vestibulocochlear deficit was only partly - but dramatically - reduced. This is in accordance with literature data, showing that a severe and permanent auditory deficit occurs at some time in the majority of patients suffering from Cogan's syndrome. Tapering off Prednisone unfortunately reactivated the audiovestibular and ocular symptoms of the disease in our patient so that a steroid-sparing immunosuppressive drug had to be added (azathioprine, followed by mycophenolate mofetil because the patient developed hepatic intolerance). Only after these therapeutic measures could the disease be stabilised. With this case report, we would like to emphasise the importance of rapidly identifying the clinical picture of Cogan's syndrome, so that immunosuppressive therapy can be started without delay, which may significantly reduce both morbidity and mortality of this disease.

A tennis player with hand claudication.

The case of a professional tennis player presenting exercise-induced hand pain with late appearance of digital blanching is reported. A bilateral hypothenar hammer syndrome and stenosis of the common palmar digital arteries close to the head of the metacarpals where the racket handle exerts its maximal force was observed with arteriography. As the patient decided to stop tennis practice, the condition improved without any medication. Six months after stopping tennis he was symptom free. Three conclusions can be drawn from this case report: 1) arteries of both hands can be injured by intense tennis practice, 2) pain in the dominant hand during tennis practice can be due to arterial insufficiency even in the absence of digital blanching which is a sign of severity, 3) hypothenar hammer syndrome is the main cause but stenosis of the common palmar digital arteries can possibly contribute to the ischemic phenomenon. Early recognition is important to avoid ineffective treatment and permanent symptoms. Therefore, we recommend an arterial examination in tennis players suffering from exercise-induced hand pain even in the absence of digital blanching which can be only a late manifestation.

The vasodilatory response of skin microcirculation to local heating is subject to desensitization.

BACKGROUND: In humans, local heating increases skin perfusion by mechanisms dependent on nitric oxide (NO). Because the vascular effects of NO may be subject to desensitization, we examined whether a first local thermal stimulus would attenuate the hyperemic response to a second one applied later. METHODS: Twelve healthy young men were studied. Skin blood flow (SkBF) was measured on forearm skin with laser Doppler imaging. Local thermal stimuli (temperature step from 34 to 41 degrees C maintained for 30 minutes) were applied with temperature-controlled chambers. We also tested the influence of prior local heating on the vasodilation induced by sodium nitroprusside (SNP), a donor of NO. RESULTS: On reheating the same spot after two hours, the response of SkBF (i.e., plateau SkBF at 30 minutes minus SkBF at 34 degrees C) was lower than during the first stimulation (mean+/-SD 404+/-212 perfusion units [PU] vs. 635+/-100 PU; P&lt;0.001). There was no such difference when reheating after four hours (654+/-153 vs. 645+/-103 PU; P=NS). Two, but not four, hours after local heating, the response of SkBF to SNP was reduced. CONCLUSION: The NO-dependent hyperemic response induced by local heating in human skin is subject to desensitization. At least one part of the mechanism implicated consists of a desensitization to the effects of NO itself.

DRIS formulas for evaluation of nutritional status of cupuaçu trees

DRIS, an Diagnosis and Recommendation Integrated System, is a tool to evaluate the nutritional status of plants. Different DRIS formulas have been proposed to improve the efficiency of the crop nutrition diagnoses. The objective of this study was to compare the nutritional diagnosis of the formulas of Beaufils (1973), of Jones (1981) and of Elwali and Gascho (1984), based on the degree of agreement in commercial orchards of Theobrama grandiflorum trees. Leaf samples of 5 to 18 year-old cupuaçu trees were collected from 153 commercial orchards in agroforestry and monoculture systems in the state of Rondonia, Brazil. Bivariate relationships between nutrition concentrations in healthy trees were used to calculate DRIS norms. DRIS indices were calculated based on the different formulas and interpreted by the Potential Fertilizer Response method, in five categories. The DRIS norms, DRIS index calculations and their interpretations were developed using the DRIS Cupuaçu computer program (www.dris.com.br). The different DRIS formulas resulted in similar diagnoses with a degree of agreement of > 90% for the nutrients N, P, K, Ca, and Mg.

Interpretação de índices dris para a cultura do cupuaçu

A produtividade dos pomares de cupuaçu na Amazônia tem experimentado lento declínio, provavelmente devido à diminuição da fertilidade do solo, requerendo adubações. Na ausência de recomendações técnicas para quantificar a demanda por nutrientes por essa cultura, o uso do Sistema Integrado de Diagnose e Recomendação (DRIS) pode representar uma alternativa para suprir essa necessidade. O objetivo deste trabalho foi avaliar os diagnósticos produzidos por diferentes fórmulas e critérios de interpretação dos índices DRIS em pomares de cupuaçu. Amostras foliares de 153 pomares foram analisadas para os nutrientes N, P, K, Ca, Mg, Zn, Mn, Cu e Fe e diagnosticadas por três fórmulas DRIS: Beaufils, Jones e Wadt e colaboradores. Na interpretação dos índices DRIS, utilizaram-se: o método DRIS Matéria Seca (M-DRIS), que separa os nutrientes em limitantes ou não limitantes, e o método do Potencial de Resposta à Adubação, o qual separa os nutrientes no estado nutricional de insuficientes, equilibrados ou em excesso. Foram também adotados níveis críticos para os teores dos nutrientes foliares em cupuaçueiros, oriundos da literatura. Os diagnósticos produzidos pelos diferentes critérios de interpretação dos índices DRIS não foram consistentes entre si ou em comparação com o método do nível crítico. A exceção foi a fórmula de Wadt e colaboradores que mostrou maior consistência entre os diagnósticos, independentemente do critério utilizado para sua interpretação. Os valores sugeridos para avaliação do estado nutricional pelo método do nível crítico não foram satisfatórios.

Pediatric tracheotomy: a 30-year experience.

BACKGROUND/PURPOSE: The aim of this study was to investigate changes of pediatric tracheotomy practice over time. METHODS: A retrospective analysis of all tracheotomies at the University Children's Hospital Zurich from January 1990 to December 2009 was performed. Data analyzed included the indication for tracheotomy, patient comorbidities, age, duration of cannulation, and complications. The second part of the study consisted of comparing our results with data from an earlier study done at the same institution by Simma et al. (Eur J Pediatr 1994;153:291-296) reviewing the patients with tracheotomies treated from 1979 to 1989. RESULTS: Between 1990 and 2009, 119 patients were included. The indication for tracheotomy was airway obstruction in 70% and prolonged ventilation in 30%. 70% of the patients were operated on before 1 year of age. Serious postoperative complications occurred in 25 patients (23%). There was one death related to tracheotomy. Successful decannulation was achieved in 60%, on average 28 months after tracheotomy. The decannulation rate in patients with airway obstruction was 74% compared to 52% for the patients in prolonged ventilation group; a statistically significant difference was observed (p < 0.05). The longitudinal analysis showed an increase of indications for prolonged ventilation and a trend toward decreased tracheotomy complications. CONCLUSION: Over 30 years, a shift in the indications of pediatric tracheotomy, with an increasing number of procedures performed for prolonged ventilation, was found. The tracheotomy-related mortality was under 1%. Tracheotomy remains a valid and safe option for pediatric patients. Level of evidence 2c.
