Objectif De nombreux patients suivis au Centre specialise de l'obesite sont touches par la precarite. Leur budget alimentation est tres reduit. De plus les personnes souffrant d'obesite pensent souvent qu'elles ne peuvent pas manger comme tout le monde. Nous avons recherche un support permettant l'application des conseils nutritionnels et respectant la problematique financiere, d'ou la creation d'un livret: « nos recettes preferees ». Materiels et methodes Les recettes nous ont ete fournies par des membres du service – dieteticien(ne)s, secretaires, infirmieres, medecins – et par des patient(e)s. Elles ont ete testees et approuvees ! Pour chacune d'elle des icones indiquent le cout (calcule avec les prix des sites de supermarches en ligne) et la composition nutritionnelle (table CIQUAL). Nous avons indique des variantes pour proposer des alternatives et encourager la creativite. Resultats Une preface explique l'origine du projet. Elle est suivie d'un calendrier des aliments selon les saisons. Une quarantaine de recettes sont categorisees: entrees, plats, desserts, snacks et sauces. Une rubrique presente les herbes aromatiques pour ameliorer des plats simples et des exemples pour reutiliser ses restes. Le livret se termine par un questionnaire de satisfaction – pour l'evaluer et le faire evoluer – et quelques pages blanches a completer avec leurs recettes. La distribution des livrets devrait debuter en 2015. Il devrait se composer de deux couvertures cartonnees, reliees en spirale, qui pourront se transformer en chevalet de cuisine. Il servira de base de discussion avec les patients en consultation dietetique. Conclusion Nous avons souhaite redonner des reperes alimentaires aux patients et leur permettre de poursuivre les efforts demandes grâce a un outil simple d'utilisation. Ce livret veut dedramatiser et simplifier la relation des patients avec la nourriture. Nous esperons que les patients proposeront de partager leurs propres recettes afin de continuer a alimenter cet outil qui est le leur. Declaration d’interet Les auteurs declarent ne pas avoir d'interet direct ou indirect (financier ou en nature) avec un organisme prive, industriel ou commercial en relation avec le sujet presente.

Equine protozoal myeloencephalitis (EPM) is a debilitating protozoal disease of the CNS that is typically caused by infection with Sarcocystis neurona and less frequently with Neospora hughesi (Sellon and Dubey 2007). Although the epidemiology of S neurona has been well characterised, the diagnostic modalities, long-term implications and response to treatment are not fully understood. The diagnosis of EPM is often based on the presence of antibodies against S neurona in serum and/or cerebrospinal fluid (CSF; Furr and others 2002). The introduction of a quantitative indirect fluorescent antibody test (IFAT) for the detection of specific antibodies against S neurona has enabled equine veterinarians to better determine the likelihood of infection in a horse with neurological deficits (Duarte and others 2004). Many equine veterinarians routinely use the IgG IFAT for S neurona to aid in the diagnosis of EPM and also to help guide treatment duration and determine when successful treatment has been achieved. However, practicing veterinarians have reported that specific antiprotozoal treatment appears not to influence reduction of antibody levels against S neurona . The goal of this study was to determine the temporal trends in antibody levels against S neurona in seropositive horses following administration of ponazuril paste. The study was performed at one large farm located in northern California. The farm had previously had confirmed cases of EPM, but there were no current cases. Prior to study commencement, 61 adult healthy, warmblood horses with no …

Hypothesis/Objectives To describe the clinical, histological and immunological findings of an equine case of pemphigus vulgaris, including the demonstration of antidesmoglein (anti-Dsg) autoantibodies. Case report The diagnosis of pemphigus vulgaris was confirmed in a 9-year-old Welsh pony stallion with both direct and indirect immunofluorescence and immunoprecipitation studies, the latter identifying circulating anti-Dsg3 IgG. Treatment with immunosuppressive medications was initiated. Lesions were seen in the perineal area, sheath, mane, tail, eyelids, coronary bands and mucosa of the mouth and oesophagus. Initial corticosteroid treatment improved the clinical signs, but the onset of laminitis necessitated a reduction in dosage, which was associated with a recurrence of lesions and development of oral ulcers. A corneal ulcer developed after 60 days of treatment. Despite treatment with azathioprine, gold salts and dapsone, the disease progressed and the pony was euthanized. Postmortem examination showed additional lesions of the cardia of the stomach. Conclusions and clinical importance Pemphigus vulgaris is rarely diagnosed in equids. We describe a case that was substantiated by the demonstration of anti-Dsg3 IgG. Response to treatment was poor, with the best response to high doses of prednisolone. Equine pemphigus vulgaris is likely to carry a poor prognosis and if there is no response to treatment, humane euthanasia is warranted. Resume Hypotheses/Objectifs Decrire les donnees cliniques, histologiques et immunologiques d'un cas de pemphigus vulgaire chez un cheval, ainsi que la mise en evidence d'auto-anticorps antidesmogleine (anti-Dsg). Cas clinique Le diagnostic de pemphigus vulgaire a ete confirme chez un poney etalon Welsh par des etudes d'immunofluorescences directe et indirecte et d'immunuprecipitations, ces dernieres mettant en evidence des IgG circulant anti-Dsg3. Le traitement a ete initie a l'aide d'immunosuppresseurs. Les lesions etaient localisees dans la region perineale, le fourreau, la criniere, la queue, les paupieres, les couronnes et la muqueuse de la bouche et de l’œsophage. Le traitement initial corticoide a ameliore les signes cliniques mais l'apparition d'une boiterie a necessite une diminution de la dose associee a une recidive des lesions et au developpement de nouveaux ulceres oraux. Un ulcere corneen s'est developpe apres 60 jours de traitement. Malgre un traitement a base d'azathioprine, de sels d'or et de dapsone, la maladie a progresse et le poney a ete euthanasie. L’examen post mortem a montre des lesions supplementaires du cardia de l'estomac. Conclusions et importance clinique Le pemphigus vulgaire est rarement diagnostique chez les chevaux. Nous decrivons un cas confirme par la presence d’IgG anti-Dsg3. La reponse au traitement a ete faible, la meilleure etant celle liee a de fortes doses de prednisolone. Le pemphigus vulgaire equin est de mauvais pronostic et en cas d'absence de reponse au traitement, l'euthanasie est recommandee. Resumen Hipotesis/objetivos Describir los hallazgos clinicos, histologicos e inmunologicos de un caso de penfigo vulgaris, incluyendo la demostracion de los autoanticuerpos frente a desmogleina (anti-Dsg). Informe de caso el diagnostico de penfigo vulgaris se confirmo en un macho pony Gales de 9 anos de edad mediante inmunofluorescencia directa a indirecta y estudios de inmunoprecipitacion. Esta ultima tecnica identifico IgG circulantes frente a Dsg-3. Se inicio el tratamiento inmunosupresor. Se observaron lesiones en la zona del perineo, vaina del pene, crin, cola, parpados, banda coronaria y mucosa de la boca y del esofago. El tratamiento inicial con corticosteroides mejoro los signos clinicos, pero la aparicion de laminitas forzo una reduccion en la dosis, lo cual produjo una recidiva de los signos clinicos y el desarrollo de ulceras en la cavidad oral. Se desarrollo una ulcera corneal tras 60 dias de tratamiento. A pesar del tratamiento con azatioprina, sales de oro y dapsona, la enfermedad progreso y el pony fue finalmente eutanasiado. Conclusiones e importancia clinica penfigo vulgaris se diagnostica raramente en equinos. Describimos un caso de esta enfermedad apoyado por la demostracion de inmunoglobulinas IgG frente a Dsg-3. La respuesta al tratamiento fue pobre, siendo la respuesta mejor con altas dosis de predinosolona. El penfigo vulgaris en equinos parece asociarse con un pronostico pobre y si no hubiera respuesta al tratamiento, se recomienda la eutanasia humanitaria. Zusammenfassung Hypothese/Ziele Eine Beschreibung der klinischen, histologischen und immunologischen Befunde eines Pferdes mit Pemphigus vulgaris, sowie auch der Veranschaulichung von Antidesmoglein (anti-Dsg) Auto-Antikorpern Fallbericht Die Diagnose Pemphigus vulgaris wurde bei einem 9 Jahre alten Welsh Ponyhengst mittels sowohl direkter, als auch indirekter Immunfluoreszenz und mit Immunprazipitationsstudien nachgewiesen, wobei letztere Methode zirkulierendes anti-Dsg3 IgG identifiziert. Eine Behandlung mit immunsupprimierenden Medikamenten wurde eingeleitet. Lasionen bestanden in der Perinealgegend, Praputium, Mahne, Schweif, Augenlider, Kronsaum und an der Schleimhaut von Maul und Speiserohre. Ursprunglich verbesserte eine Therapie mit Kortikosteroiden die klinischen Symptome, aber das Auftreten von Hufrehe machte eine Dosisreduktion erforderlich, was wiederum zum neuerlichen Auftreten der Hautveranderungen und der Entwicklung von oralen Ulzera fuhrte. Ein Hornhautulkus entwickelte sich 60 Tage nach der Behandlung. Trotz der Behandlung mit Azathioprin, Goldsalzen und Dapson verschlechterte sich die Erkrankung und das Pony wurde euthanasiert. Eine Postmortem Untersuchung zeigte zusatzliche Veranderungen an der Cardia des Magens. Schlussfolgerung und klinische Bedeutung Pemphigus vulgaris wird bei Equiden selten diagnostiziert. Hier beschreiben wir einen Fall, der durch die Darstellung von anti-Dsg3 IgG abgesichert wurde. Auf die Behandlung wurde schlecht angesprochen, wobei die deutlichste Besserung bei hohen Dosen an Prednisolon zu sehen war. Es ist wahrscheinlich, dass der Pemphigus vulgaris der Equiden eine schlechte Prognose hat und folglich ist die Euthanasie, wenn nach Behandlung keine Besserung eintritt, aus humanitaren Grunden berechtigt. 要約 仮説/目的 馬の尋常性天疱瘡の臨床的、組織学的、免疫組織学的な所見を抗デスモグレイン抗体の証明を含めて解説すること。 症例報告 尋常性天疱瘡の診断を9歳のウェルッシュポニー種牡馬で直接および間接免疫蛍光法の両方ならびに免疫沈降法を用いて行った。後者では循環血中の抗Dsg3IgGを特定した。免疫抑制剤による治療を開始した。病変は会陰部、包皮、たてがみ、尾、眼瞼、蹄冠帯、口腔と食道粘膜にみられた。最初のコルチコステロイド治療により臨床症状が改善したが、蹄葉炎の発症により減量が必要となり、それに関連して病変が再発し口腔内に潰瘍を生じた。角膜潰瘍が治療開始60日後に生じた。アザチオプリン、金塩、ダプソンを用いた治療にも関わらず、病変は進行し、ポニーは安楽死された。剖検により胃の噴門部の病変が明らかにされた。 結論と臨床的重要性 尋常性天疱瘡はウマ科の動物ではまれに診断されない。著者らは抗Dsg3 IgGの証明によって立証した症例を報告した。治療への反応は乏しく、最も反応したのは高用量のプレドニゾロンであった。馬の尋常性天疱瘡はおそらく予後は悪いため、治療に全く反応しないようなら人道的な安楽死が正当な理由となる。 摘要 假设/目的 描述寻常天疱疮患马的临床、组织学和免疫学发现,包括证明抗桥粒芯蛋白(抗Dsg)自体抗体的存在。 病例报告 用直接和简介免疫荧光和免疫沉淀反应,确诊了一匹9岁威尔士矮种马为寻常天疱疮。后者识别循环的抗Dsg3 IgG。开始免疫抑制药物治疗。可见会阴部、腱鞘、鬃毛、尾部、眼睑、冠状带与口腔和食道粘膜病变。初期的皮质醇治疗改善了临床症状, 但出现蹄叶炎迫使减少剂量。病变复发和口腔溃疡与之有关。治疗60天后角膜溃疡发展。尽管用硫唑嘌呤、金盐和氨苯砜治疗, 但疾病仍恶化, 矮种马被安乐死。尸体剖检显示胃部贲门额外的病变。 结论和临床价值 马很少被诊断出寻常天疱疮。我们描述了一个通过证明抗Dsg3 IgG存在而确诊的病例。治疗反应不良, 高剂量泼尼松龙的反应最好。马寻常天疱疮可能预后不良, 如果对治疗无反应, 应当实施人道安乐死。

Introduction of antiosteoclastic drugs, calcitonin and etidronate, has profoundly changed the treatment of active Paget's disease of bone. Nevertheless, the use of these drugs is limited in some patients by the occurrence of side-effects or by a resistance to therapy. We report the results of an open, nonrandomized study with a new bisphosphonate, (chloro-4 phenyl) thiomethylene bisphosphonate (Cl-TMBP), given orally to 35 patients with active Paget's disease of bone. At two different dosages this new bisphosphonate induced a significant decrease in disease activity. Patients receiving a mean dosage of 5 mg/kg/d (n = 14) showed a significant reduction of serum alkaline phosphatase levels to 43% of pretherapeutic values (from 499 +/- 91 to 214 +/- 41 IU/l) while hydroxyproline/creatinine ratio decreased to 43% of baseline (from 93 +/- 21 to 40 +/- 11). A second group of patients (n = 21) receiving a mean dosage of 11 mg/kg/d exhibited a similar response: serum alkaline phosphatase activity was reduced to 42% of initial values (from 1384 +/- 209 to 584 +/- 111 IU/l) while hydroxyproline/creatinine ratio fell to 48% of baseline (from 144 +/- 27 to 69 +/- 15). This was accompanied by a reduction in radionuclide uptake in pagetic areas. A prolonged beneficial effect was observed in most patients. In patients receiving the highest dosage significant reduction in serum calcium and rise in parathyroid hormone were observed. Otherwise no clinical or biological side-effect occurred throughout the study.

This paper reviews genetics of fibre production and fleece characteristics in small ruminants, Angora rabbit and South American camelids with a special distinction between single-coated (SC) and double-coated (DC) species. Considering the biology of fibre production, there are variations in coat composition and structure, fibre growth pattern and fibre structure and quality between these two main kinds of fibre-producing animals. In SC species, all fibres are nearly similar in dimensions and are produced from individual follicles that have a very long period, essentially permanent, of active growth without a synchronous phase of rest between follicles. In contrast, in DC species the fleece comprises a coarse outer coat and a fine inner coat with variations of coat composition and structure, and fibre growth pattern according to the season with a well-defined duration of fibre growth. Genetic basis of hair growth pattern, coat composition and fibre structure are different between species. In small ruminants, these coat characters are additive and because of several genes whereas in rabbit, several autosomal recessive genes determine fibre growth, coat composition and structure. In alpaca, the fleece type (Suri or Huacaya) is determined by a single dominant gene. This paper also reviews genetic parameters of fibre production traits in Angora goat, Angora rabbit and alpaca in which many aspects of the genetic basis of fibre production are analogous. There are many traits controlling both fibre quality and fibre quantity, and most of these traits tend to be moderately to strongly inherited so that a rapid genetic progress in any traits is possible and indeed has been achieved. However, there are differences in breeding programmes. In DC Angora rabbit, selection for one single trait, the easy measurable total fleece weight has general beneficial effects on fleece quality. However, because of antagonistic relations between qualitative and quantitative traits in SC species, achieving this goal requires a multi-trait selection index approach. Gene mapping studies have recently identified several putative quantitative trait loci and major genes affecting fibre and fleece characteristics in sheep, goat and rabbit are reviewed. The whole genome sequence of sheep and rabbit will be available in the near future and the use of high-density single nucleotide polymorphism chip will allow fine mapping and dissection of the genetic basis of many production traits including fibre production and fleece characteristics. The application of these techniques will thus contribute to improving the efficiency, profitability and sustainability of small ruminant and rabbit fibre production.

cattle, coat colour, MC1R. ,Animal culture ,SF1-1100 - Abstract
Most of the Western European cattle breeds consist of standardised breeds with a definite coat colour (Renieri et al., 1984). Thus coat colour could be useful to detect genetic markers for cattle breed identification. In cattle the pigmentation is determined by the distribution of two pigments: eu- and pheomelanin, producing brown or black and red to yellow pigmentation respectively. Tyrosinase, the rate-limiting enzyme involved in the synthesis of both melanins, is regulated by the melanocyte stimulating hormone (αMSH). This hormone and several other melanotropic peptides stimulate melanin formation in melanocytes by binding to the melanocortin-1-receptor (MC1R), a G-protein-coupled receptor encoded by the Extension gene (Robbins et al., 1993). In addition, the amounts of eu- and pheomelanin in the melanocyte are controlled by the agouti gene encoding the Agouti Signal Protein (ASP), that acts as an antagonist of MSH signalling through the MC1R, even if its mechanism of action is controversial (Furumura et al., 1998)..........
