Les résistances simples ou conjointes à la fluméquine et à l’enrofloxacine sont significativement plus rares chez les oiseaux de compagnie que chez ceux de production et semblent être dues à une sélection directe après traitement. Chez les oiseaux de production la fréquence des souches résistantes n’est influencée ni par l’âge, ni par la possibilité ou non de traiter les animaux (industrielle vs « bio-label »). Ces observations peuvent s’expliquer par le portage de souches résistantes dès la naissance des poussins; souches acquises au départ du cheptel reproducteur, ce dernier jouant un rôle disséminateur majeur lié à l’aspect typiquement pyramidal de la production avicole (faible nombre de parentaux qui produisent un grand nombre de volailles de production).

RÉSUMÉ : Le placement échoguidé de l’aiguille spinale pour les ponctions cisternale et lombaire chez le chien a été décrit. L’objectif de ce travail était de comparer l’effet du guidage échographique pour la ponction de liquide céphalo-rachidien entre les ponctions cisternale et lombaire. Quatre-vingt-trois opérateurs ont participé à l’étude. Ils étaient divisés en quatre groupes selon leur expérience. Après une formation théorique courte, chaque opérateur a réalisé une ponction cisternale et lombaire en aveugle et sous contrôle échographique sur des cadavres tirés au sort. L’échoguidage lombaire était direct alors que celui cisternal était indirect. Après chaque procédure, les opérateurs ont rempli un questionnaire sur leur expérience, leur performance et leur confiance en soi. L’échoguidage augmentait significativement le taux de réussite global de la ponction (comparée à la méthode en aveugle) mais plus clairement avec la localisation lombaire. Le guidage échographique cisternal améliorait significativement le nombre de tentatives, le temps et la confiance en soi chez les opérateurs inexpérimentés et expérimentés. La première cause d’échec citée était différente selon la localisation de la ponction et était liée à la nature de l’échoguidage. Cette étude démontre que les opérateurs inexpérimentés sont capables de réaliser des ponctions échoguidées après une formation théorique courte, justifiant l’utilité du guidage échographique à des fins pédagogiques.

Endoscopy of the upper airway in horses is done either at rest or during exercise, i. e. dynamic endoscopy. The present study compared observations made on 11 saddle horses botte with dynamic treadmill and dynamic field endoscopy.The results acquired with botte methods during strenuous exercise led to similar conclusions in terms of diagnosis and prognosis in 8 out of 11 cases. For the 3 others, the overground endoscopy revealed an abnormality that was net observable with treadmill endoscopy [less ▲]

Two rooms of a pig house were used to study 2 deep litter systems where the animals were kept on a 50 cm thick layer of sawdust or of chopped straw (10 cm). Seven days before the arrival of the animals, slurry and a microbial product used to stimulate the fermentation were added to the litters. Fifteen pigs on sawdust and seventien pigs on straw (floor spaces : 1.4 and 1.2 M2/pig) were fattened from 23.1 to 93.1 kg live weight. Excreta from pigs was dung into the bedding weekly and treated with the microbial product. This labour was considered as too hard in the straw room and was ended at day 105. No sawdust was added during the fattening period but straw was added 5 times to keep the pigs clean and to keep the temperature in the bedding higher than 30-degrees-C. The mean temperature in the sawdust bed was higher (38 +/- 5,4-degrees-C vs 35 +/- 6,7-degrees-C, p > 0,001) and more constant (mean daily variation 1,3 +/- 1,6 vs 2,2 +/- 2,4-degrees-C, p > 0,001) than the temperature recorded in the straw bed. The air temperature and the relative humidity were similar in the 2 rooms (21-degrees-C and 60 The concentrations of ammonia in the air were measured with Gastec tubes. The average ammonia concentrations recorded during the 7 days before the arrival of the animals (48 +/- 36 ppm vs 12 +/- 9,2 ppm) and those recorded after the eighth day (11 +/- 5,6 ppm vs 6,7 +/- 3,9 ppm) were significantly higher with the straw system compared with the sawdust system. The daily gains were not significantly different in the 2 rooms (552 g on average) and the food conversion ratios in the 2 rooms were 3,6 kg/kg (on sawdust) and 3,85 kg/kg (on straw). Carcasses were of equal quality. In conclusion, results were better with the sawdust bed than with the straw bed. The sawdust bed provided a higher temperature in the bedding and a lower ammonia concentration in the air. The routine weekly task of digging was easier in the sawdust bed and the bedding was used for a second batch. [less ▲]

OBJECTIVE: To compare changes in biochemical markers of bone turnover in postmenopausal women who received sequential discontinuous hormone replacement therapy (HRT) with either transdermal 17 beta-estradiol gel (group 1) or oral equine sulfoconjugated estrogen (group 2), plus nomegestrol acetate. PATIENTS AND METHOD: Prospective, open, randomized, controlled trial, conducted on 3 parallel groups of 106 postmenopausal women. All treated groups received estrogen therapy for 25 consecutive days every month. The estrogen used was either 1.5 mg/day of transdermal 17 beta-estradiol gel (group 1) [N = 42, average age (AA) = 51.6 years, average duration of menopause (ADM = 21.5 months)], or 0.625 mg/day of oral equine sulfoconjugated estrogen (group 2) [N = 39, AA = 51.3 years, ADM = 16.8 months]. In all cases nomegestrol acetate 5 mg/day was added for 12 consecutive days every month. The control group comprised 25 patients, [AA = 53.4 years, ADM = 33.7 months]. Two bone resorption markers: urinary cross-linked N-telopeptide and C-telopeptide of type I collagen (U-NTX/Cr, U-CTX/Cr), and a bone formation marker: serum bone specific alkaline phosphatase activity were measured before and 6 months after treatment start. RESULTS: Significant decreases from baseline values were observed for the 3 biochemical markers in both treated groups compared with control (P < 0.001). There were no significant differences in changes between the 2 treated groups for the 3 biochemical markers. The mean percentage change in the 3 biochemical markers was: from -9.3 to -45.5% in group 1, from -20.5 to -39% in group 2, and from -3.3 to 2% in control group. In group 1, the mean percentage decreases in U-CTX reached optimal threshold of bone turnover change (-45%) which is considered by the International Osteoporosis Foundation as clinically relevant because it predicts an increase in BMD greater than 3% when treatment is maintained over a long term. DISCUSSION AND CONCLUSION: Both treated groups induced a significant comparable decrease of bone turnover markers after 6 months of intervention, compared with control. The group treated with cyclic administration of transdermal 17 beta-estradiol (1.5 mg/day) and nomegestrol acetate (5 mg/day) showed a bone resorption markers decrease corresponding to the threshold of clinical relevance described in the international literature and predictive of positive BMD response in long term.

Aims The aim of this study was to evaluate the impact of “VeinoPlus Sport” on amateur soccer players’ recovery after an intense physical activity (2 drills). Method We proceeded to a comparative study between two devices: “VeinoPlus Sport” and “TENS” (used as a control system) on a population of 20 players (average age 17,1±0,8). Under identical conditions each player used the two devices during two separate sessions (called group “VeinoPlus Sport” and group “TENS”). The players performed an intense effort following the YoYo test concept. Four blood samples were taken from each participant and a Myotest evaluation was performed: one before the test, one just after the first intense effort, another after a short recovery time following the first effort, and the last one right after the second intense effort. For statistical analysis, we used the Anova algorithm of the “StatPlus” system and a Scheffé test. Results With both devices, we observed a significant elevation of lactate, HCO3− ions, and myoglobin as time progressed. The analysis of other blood parameters did not show any significant evolution in the course of the testing. The “VeinoPlus Sport” group, after the session, expressed feeling lighter and more fit than usual following an intense physical activity. They did not suffer any pain, tiredness, nor diminishment of strength. The same observation was made with the “TENS” group with the exception that some players felt a bit of soreness in their thigh and calf areas. In general, all participants admitted preferring the use of recovery machines instead of natural recovery. At the same time, none expressed any preferences between either of the devices. Conclusion The main asset of this study resided in the highlighting of minor differences as no way significant between the two machines tested on the chosen population. The “TENS” shows similar results as the “VeinoPlus Sport” even if a slight preference for the latter was expressed. Both devices permitted an equal or even better performance in the second drill in comparison to the first drill. [less ▲]
