Anthocyanins are colorants which provide most of the blue, red and violet colours in numerous plants and fruits. Because of their great sensitivity to the slightest changes in pH and their instability in ordinary daylight, it is generally thought that these colorants were used only to dye everyday clothes in a domestic context. However, medieval artists’ recipe books not only describe these elusive substances, but also indicate their use in illumination. This is notably the case for the texts of the so-called ‘Strasbourg Tradition’, written in the south of Germany and the north of France between 1400 and 1560, and partly composed from an older Alsatian treatise on illumination. Departing from these sources, this paper details the methods employed to prepare these colorants and (re)evaluates their diverse uses in painting and illuminating techniques. This technical data subsequently served as a basis upon which to make reconstructions. Finally, an attempt to correlate the information provided by these recipe books with specific artistic practices was carried out by collating the descriptions with the results of analyses from contemporary illuminations by an Alsatian workshop active in the same geographical area.

Due to their trade value, a huge range of artistic materials are documented and recorded in historical written sources. However, certain substances are not registered in these archives because they did not have a market value. This is especially the case for vegetal species which artists easily found in nature and used for their colouring principles, like anthocyanin colorants. As they are characterized by a great sensitivity to the slightest changes in pH and as they are highly unstable in ordinary daylight, these colorants were not frequently used in the dyeing of quality materials or in painting. Up until now, they have been mainly considered as being used in a domestic context, for the dyeing of everyday clothes. Moreover, after ageing, the plant species are difficult to identify with currently-used analytical methods. We therefore intend to bring to light these « elusive » substances through the close examination of an original and primordial source : artistic recipe books. Our previous researches have highlighted that these books not only describe these organic colorants, but that they also indicate their use in illumination. From the 14th to the 16th century, hundreds of recipe books containing information relating to these colorants were produced. They describe both their preparation, their diverse applications and the required conditions for their conservation. These recipe books also inform us about the different hues obtained from these colorants. Our study will involve analysing the significance of these organic substances as well as (re)defining their use with a view to increasing our knowledge of historical artistic practices and materials. Furthermore, it could also help to identify specific artistic productions or workshops. Finally, it would be possible to learn more about the status of artists, their working conditions and their training. [less ▲]

The distal extension of ascending aorta pathology often requires prosthetic grafting into the proximal arch. In order to perform optimal distal anastomosis, an open technique under a short period of circulatory arrest (CA) was adopted. For this purpose we evaluated prospectively a simplified technique for surgery and perfusion. The aneurysmal aorta was directly cannulated to cool down the patient to 26 degrees C. Under CA and retrograde cerebral perfusion, the diseased aorta and aortic cannulation site were resected. After completion of the distal anastomosis, antegrade rewarming was performed via recannulation of the AAo graft (side branch graft) whilst surgery was proceeded on the root and/or aortic valve. This technique clearly addresses the safety of cannulation into the aneurismal aorta. The issues of cerebral and visceral protection during CA and antegrade reperfusion and rewarming have been analysed prospectively in eight patients operated on over a period of 6 months. Our preliminary results indicate that this technique of arterial cannulation and CA at 26 degrees C for the management of degenerative AAo disease involving the proximal arch appears safe both in terms of cerebral and systemic (visceral, muscular) protection. By this way, the complications related to deep hypothermia and prolonged cardiopulmonary bypass are avoided. This assumption may be only valid for a CA period less than 30 min. This preliminary study is limited by its small size and heterogeneity of the pathologies. However, the simplicity, surgical ease, rapidity and efficacy conveyed by this technique warrant further consideration and evaluation. [less ▲]

Philadelphia-positive chronic myelogenous leukemia (CML) is a rare disease in children and constitutes approximately 3-5% of all childhood leukemias. With tyrosine kinase inhibitors (TKI), the frequency of accelerated phase (AP) or blast crisis (BC) is remarkably reduced, estimated to 1% to 1.5% per year in adults compared with more than 20% per year in the pre-TKI era. But no data are available among children. Purpose: We described the characteristics, the treatment and the outcome of 21 children with CML, who evolved in accelerated phase and/or blast crisis under TKI. Results: From 2001 to april 2015, 415 European patients were enrolled in the CML pediatric database. Twenty-one patients (5.1%), in chronic phase (CP) treated by TKI, presented AP or BC. The median age of AP /BC cohort was 13.2 years (range: 4.5-16.9 years) with a sex ratio M/F at 2. At CML diagnosis, 15 patients (71%) had high risk Sokal Score with a median score of 1,4 (range: 0,16-2,4). All patients harbored t(9;22)(q34;q11) but one had a complex translocation t(1;9;22)(q12;q34;q11) and another one presented additional inv(3)(q21q26). Imatinib was the first line TKI for all patients. Before AP or BC, only five patients (24%) obtained a complete cytogenetic response (CCyR) and three achieved MMR. For incomplete molecular response or progression to accelerated phase, 8 patients (38%) were switched to dasatinib. Median duration of TKI before AP or BC was 11 months (range: 3 months-56.5 months). Six patients evolved to AP with a median interval of 8.7 months (range: 1 months-24 months), leading to blast crisis for 4 patients with a median time of 3.5 months (range: 0.3-5.4 months). Among the 2 patients remaining in AP, imatinib was increased for one and the other was switched for dasatinib, all before hematopoietic stem cells transplantation (HSCT). One patient died of post-transplant complication and the other one is still alive in complete molecular response without TKI. Nineteen patients presented BC, including 4 after AP. Thirteen patients (62%) presented ALL, five (24%) AML and one a bi phenotypic leukemia. Central nervous system (CNS) was involved for two patients with ALL, one isolated, one combined. At AP or BC, nine patients (43%) presented new additional cytogenetic abnormalities. Eighteen patients with BC were treated according to AML or ALL protocols, combined with second generation TKI for twelve patients. Only one patient underwent preparative regimen, without intensive chemotherapy before HSCT. Ten patients reached complete remission. Four patients died before HSCT, by progressive disease for 2 and by fatal infection for 2. Overall, 15 patients in BC were transplanted. Before HSCT, median molecular response was 0.2% (range: 0-29%) and only four patients had a complete molecular response. After transplant, seven patients received second generation TKI. Four patients died, including three related to transplant toxicity. Thirteen patients were alive, but one with ALL BC relapsed 26 months post-transplant and was waiting for second HSCT. With a median follow-up of 4.4 years, 4-year overall survival was 59% (66% for ALL BC versus 40% for AML BC). Conclusion: Incidence of AP/BC after imatinib for CP CML is at 5%, in the CML pediatric database. Despite second generation TKI, combined with HSCT, outcome remains poor. Post-transplant indication of TKI is heterogenic. Recommendations would be useful for practice. [less ▲]

La fièvre catarrhale ovine (FCO) a été identifiée au Nord de l’Europe <br />le 14 août 2006. L’Allemagne, la Belgique, les Pays-Bas et, dans une <br />moindre mesure, le Grand-Duché de Luxembourg et la France ont été <br />affectés. Le sérotype 8 du virus de la FCO (exotique) a rapidement été <br />identifié ainsi qu’un vecteur, Culicoides dewulfi, une espèce indigène du <br />Nord de l’Europe. La maladie s’est rapidement développée et au 1er <br />février 2007, on recensait 2137 foyers de FCO, toutes espèces de <br />ruminants confondues. Globalement, la maladie a affecté davantage les <br />bovins (54 %) que les ovins (46 %). Les signes cliniques les plus <br />fréquemment observés chez les bovins étaient des lésions sur le museau <br />et la cavité buccale (ulcérations/croûtes), de la salivation et des boiteries <br />chez des animaux adultes. La morbidité et la mortalité animales étaient <br />respectivement de maximum 5 % et 1 %. Les principaux signes cliniques <br />rencontrés chez le mouton étaient également des lésions sur le museau <br />et la cavité buccale (ulcérations/croûtes), de l’amaigrissement et des <br />boiteries. La morbidité et la mortalité animales étaient respectivement <br />de maximum 12 % et 6 %. Les signes cliniques n’étant pas <br />pathognomoniques et le diagnostic différentiel relativement vaste, seul <br />un examen de laboratoire permet d’établir un diagnostic de certitude. [less ▲]

The present paper describes chondrodystrophy (perosis) in three poultry units producing labelled chickens. An unilateral deviation of a hind leg along with a tumefaction of the tarsal joint appeared in 4-day- to 4-week-old birds; 5 to 50% of the animals were affected. The growth rate was reduced and cachexia was also observed. There were also breast blisters. Chemical analyses were carried out on the poultry feed in two of the units. The manganese content was below the requirements at about 35 mg/kg; in one unit, the ionic balance (Na+K-Cl) was insufficient along with a too narrow Ca/P. The insufficient supply in manganese was corrected by the addition of manganese sulfate in water at a rate of 120 g/litre of water. Manganese sulfate was also added in the feedstuff at a rate of 120 g/ton. [less ▲]
