RESUMO

Vaccination is one of the most important control tools to reduce Salmonella in poultry production. In order for a live vaccine to be licensed for field use it should be provided with the detection methods to differentiate it from field strains. This paper aims to describe the validation of an alternative method for the differentiation of the Salmonella 441/014 vaccine strain from field strains, using a chromogenic Media, ASAP from bioMérieux. The ASAP-based differentiation method was compared with already authorized methods, namely the Anicon SE Kylt PCR DIVA 1 assay and Ceva S-Check Salmonella differentiation kit, following the ISO 16140-6:2019 validation method guidelines. A Generalised Linear Model was fitted to the data to determine the inclusivity and exclusivity of differentiation methods (PCR Kylt vs. S-Check vs. ASAPTM). Statistical differences were based on a P-value level of < 0.05 (SPSS Inc., Chicago, IL). In this study, we show that the ASAP media was able to differentiate Salmonella Enteritidis vaccine strains from field strains, obtaining 100% agreement between the three differentiation assays. This differentiation approach is quicker, easier to deploy and cheaper as compared to alternative methods.

RESUMO

Chickens intensively selected for accelerating growth rate and enhanced muscle mass has resulted in the occurrence of breast alterations with a negative consumers perception. Together with the already known breast abnormalities (White Striping, Wooden Breast and Spaghetti Meat) a new one has been described by the consumers as a "long and thin worm". For this reason, the aim of this work was to macroscopically and microscopically describe this structure in broiler breast. To this end, 2 different experiments were performed. In the first one, 4 broiler breasts from a supermarket were analysed. Thereafter, a second experiment was carried out on an experimental farm simulating field management conditions in order to confirm the results of the first experiment. To this end, 120 chickens were reared in an experimental farm up to 42 d. Breast samples were collected and analysed macroscopically and microscopically to assess the abnormality on the broiler breast. In both experiments, the results of the analysis showed the finding of tubular structures located on the surface of pectoralis major muscle compatible with arteries. So far, currently, this occurrence has not been described in the literature and we propose calling this new broiler breast feature as breast-vessel.

RESUMO

The infectious bursal disease (IBD) virus is one of the most resistant and prevalent virus worldwide in the poultry industry, being vaccination the main tool to control the disease. For this reason, consistent and uniform immunization of broiler flocks against IBD is necessary to avoid the disease spreading. The aim of this study was to apply and assess an epidemiologic mapping tool focused on the immunization by in ovo single broiler vaccination using an immune complex IBD vaccine. With this regard, 7,576 serum samples were collected from 603 broiler flocks raised in 354 Spanish farms. To do so, blood samples were randomly collected from birds with ages between 35 to 51 d, and the serum was analyzed by ELISA. The results obtained from this study suggested a high uniform immunization against IBDV and a protective immunization between 35 and 51 d of age, with mean titer values ranging between 6,331 and 7,426. In addition, seroprevalence titer data of this large-scale monitoring study fitted a polynomial equation with a R2 value of 0.77, helping to explain and predict the humoral response to IBD vaccination. This seroprevalence map was applied to broiler production and was based on business intelligence tool that incorporates newly developed mapping tool to cover the need of having real-time information of humoral response to IBD vaccination and could be an effective tool for veterinary services to control and prevent IBD.

RESUMO

OBJECTIVE: Conservative and surgical treatments for meniscal lesions are various and this field of orthopedic surgery is in continuous development. Stem cells represent one of the current options to stimulate meniscal healing. The present systematic review aimed at summarizing the state of art in the application of stem cells for the treatment of meniscal damage both at pre-clinical and clinical level. MATERIALS AND METHODS: The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed to perform this systematic review. A systematic search was performed using the PubMed (MEDLINE), EMBASE and Cochrane Library databases. All the studies dealing with the application of stem cells as a treatment for meniscal tears were pooled, data were extracted and analyzed. The studies were divided into two groups (pre-clinical and clinical), and then, discussed independently. RESULTS: A total of 18 studies were included. Thirteen were classified as "pre-clinical" and five as "clinical". The most commonly used cells were mesenchymal stem cells (MSC), derived from bone marrow (BMMSC), synovial tissue (SMSC), or adipose tissue (ADSC). Follow-ups ranged from 2 to 16 weeks for the pre-clinical studies and from 3 to 24 months for the clinical studies. All studies documented good results in terms of laboratory markers/scores, clinical and radiologic evaluation. CONCLUSIONS: Based on the currently available data, it is not possible to establish the best cell source or delivery method for the treatment of meniscal injuries. Bone Marrow derived stem cells delivered through injection represent the most studied approach, with the most promising results. However, the full impact of these therapies through their different sub-type of stem cells and implantation techniques still needs to be critically analyzed through larger randomized controlled trials with longer follow-up.

RESUMO

Thermophilic Campylobacter spp. are recognized as a major cause of acute bacterial diarrhea in humans, with broiler meat being the most common source of human infection. Antibiotic therapy is usually necessary for severe or prolonged infections, especially in immunocompromised populations such as young or elderly individuals. However, different studies have demonstrated a close association between antibiotic use in animal production and antimicrobial resistance (AMR) in humans. In this sense, there is social pressure to reduce antibiotic administration and find adequate alternatives to control the presence of bacterial infections in farms. However, there is a lack of information related to Campylobacter AMR dynamics through the entire production system from breeders to their progeny. It is unknown if resistance genes are a result of adaptation through chromosomal mutation or through horizontal gene transfer, instead of vertical transmission of DNA from the parent to their progeny. Thus, the main objectives of this study were to assess the main AMR rates present in a poultry production system, to study the relationship between Campylobacter AMR profiles from breeders and their progeny, and to study the presence and distribution of antibiotic resistance genes in poultry production. Regarding AMR rates, ciprofloxacin was classified as extremely high, followed by nalidixic acid and tetracyclines that were classified as very high. Moreover, this study demonstrated a relationship between the AMR patterns and genes found from Campylobacter strains isolated in breeders and those present in their progeny.

RESUMO

Salmonellosis represents an important public health concern. Several authors point out the inefficiency of the cleaning and disinfection protocols to remove the bacteria from the field. For this reason, innovative techniques, as bacteriophages, could be implemented to control the bacteria. The main objectives of this study were to assess the effect of bacteriophages against Salmonella Infantis and Salmonella Enteritidis on farm surfaces, and to evaluate bacteriophage procedure application as sanitiser against Salmonella in field conditions. Thus, most prevalent serovars in poultry production were selected (Salmonella Infantis and Salmonella Enteritidis) to contaminate farm facilities. Then, two specific bacteriophages isolated from poultry faeces were applied against them. Results showed Salmonella Infantis and Salmonella Enteritidis decreased of 4.55 log10CFU/mL and 3.85 log10CFU/mL, respectively; the maximum reduction in Salmonella was the 5th day, after 108 PFU/mL and 103 PFU/mL bacteriophage application. These results highlight bacteriophages as a promising tool together with cleaning and disinfection.

RESUMO

Notwithstanding the National Salmonella Control Programs, the latest data published by the European Food Safety Authority show an increase in Salmonella Enteritidis prevalence in laying hen flocks. For this reason, the implementation of innovative techniques such as phage therapy is needed to control Salmonella at farm level. Most common bacteriophage applications are a cocktail of 2 or more bacteriophages, as it has been described that cocktails could remove different Salmonella serotypes, thus providing cross efficacy. Nevertheless, resistance to the bacteriophage cocktail has been reported, resulting in a decrease in their effectiveness. Along these lines, some authors have reported the possibility of using autophage when commercial bacteriophage cocktails are not active against field strains. To our best knowledge, no autophage (bacteriophage isolated from the same environment where the pathogen is isolated) has been found to control Salmonella in laying hens. In this context, the aim of this study was to assess the application of autophage in reducing Salmonella Enteritidis in environmental and fecal samples in a layer farm. To this end, the bacteriophage was isolated from the same farm where the bacteria was present and was applied onto the facility installations and the animals, at 2 different times. After bacteriophage challenges, swab cloths from facility surfaces and feces samples were collected at 3 times according to the time spent after the bacteriophage challenge. The results obtained in our study showed that all the surface samples collected from the farm facilities after phage therapy were negative for Salmonella. Concerning faces samples, statistical differences were found in Salmonella counts, with the strongest decrease (1.78log10) occurring after the second challenge. Otherwise, depending of the moment of sampling, the results obtained were 2.34log10, 1.39log10, 0.56log10, and 0.97log10 cfu/g for T0, T1, T2, and T3 respectively. The study highlights the use of autophage therapy not only for Salmonella Enteritidis control in animals, but as a sanitizer in cleaning and disinfection.

RESUMO

The aim of this study was to design and implement a dynamic prevalence map for managing the data collected within the framework of the Salmonella spp. National control plan in broiler flocks, using a data set from the Valencian Community, Spain. Such a map would be a useful tool for veterinarians seeking to define control options. The development of the mapping tool for this study involved three main phases: data collection, data analysis and data representation. The data used were obtained from the results of the National Control Programme (based on European Commission [EC] Regulation No. 2160/2003). The Salmonella prevalence data were represented on a map of the Valencian Community, which included geographical information on flock locations to facilitate the interpretation of the results from monitoring. The average prevalence of Salmonella spp. was 2.74% from 2009 to 2013. Moreover, the proportion of broiler flocks that remained positive for the target serovars according to EC Regulation No. 2160/2003 (S. Enteritidis and/orS. Typhimurium [including monophasic S. Typhimurium]) was less than 1%. Over the five-year period of the study (2009-2013), the area of Bajo Maestrazgo had the highest level of Salmonella spp. prevalence every year, thereby validating the usefulness of this mapping tool. The aim of the study is to detect geographical 'highpressure' Salmonella zones over time and make suggestions on where efforts should be focused in this region to reduce future Salmonella spp. prevalence. Local Veterinary Services could, using the map, identify the infection pressure of Salmonella in the geographical areas where farms are located. Proximity to higher prevalences may imply an increased risk of flock contamination. Although annual data are represented, data can be presented in real time with regular frequency (daily, weekly, monthly or quarterly) or even over periods of several years. Therefore, the dynamic prevalence map provides extremely useful epidemiological information to veterinarians on the prevention of Salmonella.


L'étude présentée par les auteurs visait à concevoir et mettre en application une carte dynamique de la prévalence afin de gérer les données collectées dans le cadre du plan national de contrôle des Salmonella spp. dans les cheptels de poulets de chair à partir des informations transmises par la Communauté valencienne (Espagne). L'objectif attendu était que cette carte puisse aider les vétérinaires à définir la meilleure stratégie de lutte. La conception du logiciel de cartographie s'est faite en trois étapes, portant respectivement sur la collecte, l'analyse et la représentation des données. Les données utilisées provenaient des résultats du Programme national de lutte (basé sur le Règlement [CE] n° 2160/2003 du Parlement européen et du Conseil). Les taux de prévalence de Salmonella ont été reportés sur une carte de la Communauté valencienne, qui contenait également des informations géographiques relatives à la localisation des élevages afin de faciliter l'interprétation des résultats du suivi. De 2009 à 2013, la prévalence moyenne de Salmonella spp. était de 2,74 %. En outre, le pourcentage de cheptels de poulets de chair restant positifs au regard des sérovars visés par le Règlement CE n° 2160/2003 (S. Enteritidis et/ou S. Typhimurium [y compris la souche monophasique de S. Typhimurium]) était inférieur à 1 %. Sur les cinq années de l'étude (2009­2013), la prévalence annuelle la plus élevée de Salmonella spp. restait concentrée dans la région de Bajo Maestrazgo, ce qui confirme l'utilité de cet outil cartographique. Le but de l'étude est de pouvoir détecter les zones géographiques à « forte pression ¼ de Salmonella dans le temps afin d'orienter en conséquence les efforts de lutte dans cette région et de réduire ainsi la prévalence des Salmonella spp. à l'avenir. Grâce à cette carte, les Services vétérinaires locaux pourront connaître la pression exercée par Salmonella dans les zones géographiques où se situent les élevages. La proximité des zones à forte prévalence peut représenter un risque accru de contamination des cheptels. L'outil propose par défaut une représentation annuelle des données mais celles-ci peuvent également être présentées en temps réel à intervalles réguliers (fréquence quotidienne, hebdomadaire, mensuelle ou trimestrielle), voire même sur des périodes couvrant plusieurs années. Ainsi, la carte dynamique des prévalences fournit aux vétérinaires des informations épidémiologiques extrêmement utiles pour la prévention de Salmonella.


Los autores describen un estudio encaminado a concebir y realizar un mapa dinámico de prevalencia para explotar los datos obtenidos como parte del plan nacional de lucha contra las salmonelas en bandadas de pollos asaderos, utilizando para ello un conjunto de datos correspondientes a la Comunidad Valenciana (España). Semejante mapa ofrecería a los veterinarios una herramienta útil para definir las fórmulas idóneas de lucha. La elaboración del dispositivo de cartografía para este estudio entrañaba tres grandes fases: la de obtención, la de análisis y la de representación de los datos. Los datos utilizados derivan de los resultados obtenidos con el Programa Nacional de Control (basado en el Reglamento de la Comisión Europea [CE] Nº 2160/2003). Para facilitar la interpretación de los resultados obtenidos con la labor de vigilancia, los datos de prevalencia de salmonelas fueron representados en un mapa de la Comunidad Valenciana que contenía información geográfica sobre la localización de las bandadas. De 2009 a 2013, la prevalencia media de Salmonella spp. fue del 2,74%. Por otra parte, la proporción de bandadas de pollos asaderos que seguían siendo positivas para las serovariantes estudiadas con arreglo al Reglamento (CE)Nº 2160/2003 (S. Enteritidis y/o S. Typhimurium [incluida S. Typhimurium monofásica]) era inferior al 1%. En el quinquenio cubierto por el estudio (2009­2013), la zona del Bajo Maestrazgo registró cada año la mayor prevalencia de salmonelas, hecho que confirmó la utilidad de esta herramienta cartográfica. El estudio tiene por objetivo determinar a lo largo del tiempo las zonas geográficas de 'alta presión' de salmonelas y hacer propuestas sobre las áreas de esa región en las que convendría centrar el trabajo para reducir en el futuro la prevalencia de salmonelas. Empleando el mapa, los Servicios Veterinarios podrían determinar la presión infecciosa de salmonelas en las zonas geográficas en que se encuentran las explotaciones. Cuanto más cerca esté una explotación de zonas con niveles altos de prevalencia, mayor puede ser el riesgo de contaminación de las bandadas. Aunque en el mapa se representan datos anuales, también es posible presentarlos en tiempo real con determinada periodicidad (diaria, semanal, mensual o trimestral) o incluso cubrir periodos de varios años. El mapa dinámico de prevalencia proporciona así a los veterinarios información epidemiológica de gran utilidad para la prevención de las salmonelosis.

RESUMO

The demand for evidence-based health informatics and benchmarking of 'good' information systems in health care gives an opportunity to continue reporting on recent papers in the German journal GMS Medical Informatics, Biometry and Epidemiology (MIBE) here. The publications in focus deal with a comparison of benchmarking initiatives in German-speaking countries, use of communication standards in telemonitoring scenarios, the estimation of national cancer incidence rates and modifications of parametric tests. Furthermore papers in this issue of MIM are introduced which originally have been presented at the Annual Conference of the German Society of Medical Informatics, Biometry and Epidemiology. They deal as well with evidence and evaluation of 'good' information systems but also with data harmonization, surveillance in obstetrics, adaptive designs and parametrical testing in statistical analysis, patient registries and signal processing.

RESUMO

At present, most documentation forms and item catalogs in healthcare are not accessible to the public. This applies to assessment forms of routine patient care as well as case report forms (CRFs) of clinical and epidemiological studies. On behalf of the German chairs for Medical Informatics, Biometry and Epidemiology six recommendations to developers and users of documentation forms in healthcare were developed. Open access to medical documentation forms could substantially improve information systems in healthcare and medical research networks. Therefore these forms should be made available to the scientific community, their use should not be unduly restricted, they should be published in a sustainable way using international standards and sources of documentation forms should be referenced in scientific publications.

RESUMO

The publication of a memorandum on improving medication safety by information technology in both the German journal GMS Medical Informatics, Biometry and Epidemiology (MIBE) and the journal Methods of Information in Medicine (MIM) gives reason to strengthen cooperation of MIBE and MIM and to report on more publications of MIBE here. The publications in focus deal with simulation-based optimization of emergency processes, handling of research data in publications, open access to research metadata, reliability of digital patient records in medical research, assessment methods for physical activity, using of insurance databases for epidemiological studies, certificates for epidemiological professionals, regression models, computer based training, and performance management in Swiss hospitals. Finally determining factors for scientific careers are discussed.

RESUMO

Coccidiostats could be phased out as feed additives before 1 January 2013 for public health and food safety reasons, and, as a replacement, bioactive compounds found in plants are currently being investigated since they are more likely to be found acceptable by consumers. The aim of our study was to evaluate the effect of cinnamaldehyde (CIN) and Echinacea purpurea plant extract (EP) as additives by analyzing the performance traits, oocyst excretion and intestinal lesions following experimental infection with Eimeria acervulina. A total of 72 Ross male broilers were raised from 1 to 35 d and randomly assigned to four dietary treatments: control, without additives (C); 150 mg kg(-1) cinnamaldehyde (CIN); 1000 mg kg(-1)E. purpurea plant extract (EP); 150 mg kg(-1) cinnamaldehyde plus 1000 mg kg(-1)E. purpurea plant extract (CIN+EP). At 25 d, 12 chickens per treatment were orally infected with E. acervulina. Coccidia infestation led to lower performance but with no significant differences between the infected groups. Oocyst output reached its peak from 6 to 9 d post-infection in all treatments. At duodenal level, gross lesion scores were lower for cinnamaldehyde diets (P<0.05). A similar trend was observed in the microscopic lesion scores, with a non-significant reduction as a result of cinnamaldehyde addition (P>0.05). Scoring methods for macro- and microscopic lesions showed a positive linear relationship (G=+0.70). Further studies are necessary to assess the possible anticoccidian action of the cinnamaldehyde and its value as an alternative or adjunct in therapeutic or prophylactic strategies.

RESUMO

Microbial pathogens of the genus Salmonella are among the leading causes of foodborne illness in the world. The present study was done on a laying hen farm with a Salmonella enterica serovar Enteritidis-positive result according to the testing specified by European regulation 2160/2003. The aim of this study was to compare the Salmonella contamination on a laying hen farm with the Salmonella presence in the hen eggs. The strains were isolated by ISO method 6579:2002 (standard method for the detection of Salmonella spp. in the European regulation for food and animal feeding stuffs, animal feces, and environmental samples from the primary production stage, including poultry farms) and were confirmed as Salmonella Enteritidis by the Kauffmann-White method. In addition, strains were compared with genomic macrorestriction followed by pulsed-field gel electrophoresis. Four types of samples, namely, feces (n = 50), cloacal swabs (n = 150), eggshells (n = 50), and egg contents (n = 50), were taken from each of 50 randomly selected battery cages. Results demonstrated that feces (92%) were the most positive sample, followed by eggshells (34%) and cloacal swabs (4%). No Salmonella spp. were detected in the egg contents. Our results show that a Salmonella Enteritidis-positive result on a laying hen farm, according to the testing specified by European regulation 2160/2003, did not imply the presence of the pathogen in the egg contents. Additionally, XbaI-digested genomic DNA of Salmonella Enteritidis strains isolated from several samples resulted in the same pattern, so were probably of the same origin.

RESUMO

The aim of this study was to assess the effect of carvacrol supplement as a dietary additive to rumen fermentors, fed a barley seed:alfalfa hay (70:30) ration and to compare its effect with monensin supplementation. The material was incubated with goat ruminal fluid and four different treatments were included: no additive (C), 7.5 mg/l monensin (M), 250 mg/l carvacrol (C250) and 500 mg/l carvacrol (C500). The addition of carvacrol reduced in vitro dry matter (DM), crude protein (CP) and neutral-detergent fibre (NDF) digestion. The effects induced by C250 on DM digestion at 72 h of incubation were comparable with those of M, whereas a greater reduction was obtained when carvacrol was supplemented at 500 mg/l concentration (68.9, 68.5 and 53.0 v. 76.1% for M, C250 and C500 v. C, respectively). The reduced CP potential degradability by supplements (51.2, 53.9 and 51.5 v. 72.8% for M, C250 and C500 v. C, respectively) was mainly caused by a reduction of the slowly degradable fraction. Volatile fatty acid (VFA) profiles determined after 48 h of incubation showed C250 increased butyrate and decreased acetate proportions, whereas M mainly stimulated propionate proportions, suggesting that the mechanism of action of carvacrol and M differs. C500 significantly reduced total VFA production. Carvacrol could be of great interest for its usage as a potential modulator of ruminal fermentation. Future research, including in vivo studies, in order to understand the factors that contribute to its antimicrobial activity and the selection of the optimal dose is required.

RESUMO

Three experiments on Ross broiler chickens were conducted in 3 locations: cages (Experiment 1), floor pens (Experiment 2), and commercial farms (Experiment 3). The effect of low-total P (TP) wheat-soybean based diets plus microbial phytase (Natuphos) was evaluated. Four experimental starter and finisher diets were used in a 2-phase feeding program, as follows: control diet (SC until 21 d, FC from 22 to 42 d); 2 diets (SL400 and SL600 until 21 d, FL400 and FL600 from 22 to 42 d) with low TP (0.61% for starter and 0.54% for finisher), including 400 and 600 U/kg of phytase, respectively; and a very low-TP (0.52% for starter and 0.44% for finisher) diet (SVL600 until 21 d, FVL600 from 22 to 42 d) with 600 U/kg of phytase. In Experiment 1 (broilers in cages had movement limitation and no access to litter), no differences in BW, tibiotarsus mineralization, or mineral metabolism were observed among diets. In Experiment 2 (broilers in floor pens had movement limitation and access to litter), at 21 d of age, the lowest tibiotarsus ash percentage and BW were shown by birds fed the SVL600 diet. At 42 d of age, broilers fed the FC diet were the lightest. For the rest of the parameters of tibiotarsus mineralization and mineral metabolism measured in Experiment 2, no differences were shown. In Experiment 3 (broilers in commercial farms had access to litter without movement limitation), the BW of broilers fed the SC diet was the highest at 21 d of age. At 42 d of age, the broilers fed FL400 and FL600 diets were the heaviest. At the end of Experiment 3, broilers fed the FC diet had the highest dry litter Ca and P, whereas broilers fed the FVL600 diet had the lowest values. In conclusion, the very low-TP wheat-soybean based diet supplemented with 600 U/kg of phytase was sufficient to optimize all the parameters measured in Experiment 1 but not in Experiments 2 and 3. Therefore, when evaluating Ca and P in phytase-supplemented diets for broilers, it is necessary to bear in mind the environmental conditions of experimentation.

RESUMO

OBJECTIVES: To report about the themes and about experiences with practicums in the management of information systems in health care settings (health information management) for medical informatics students. METHODS: We first summarize the topics of the health information management practicums/projects that the authors organized between 1990 and 2003 for the medical informatics programs at Heidelberg/Heilbronn, Germany, UMIT, Austria, as well as for the informatics program at the University of Leipzig, Germany. Experiences and lessons learned, obtained from the faculty that organized the practicums in the past 14 years, are reported. RESULTS: Thirty (of 32) health information management practicums focused on the analysis of health information systems. These took place inside university medical centers. Although the practicums were time-intensive and required intensively tutoring students with regard to health information management and project management, feedback from the students and graduates was mainly positive. DISCUSSION: It is clearly recommended that students specializing in medical informatics need to be confronted with real-world problems of health information systems during their studies.

RESUMO

Se describe el tratamiento quirúrgico que realizamos en las úlceras por presión Enis-Sarmiento grado III-IV en lesionados medulares, así como los cuidados preoperatorios y postoperatorios según los protocolos del Instituto Guttmann de Barcelona. Se han seleccionado 59 pacientes intervenidos entre junio de 1999 y julio de 2002, con úlceras por presión Enis-Sarmiento grado III-IV intervenidas ya en varias ocasiones. En todos los casos se practicó extirpación de la úlcera según técnica del “pseudo tumor de Guttmann”. Es fundamental que la cobertura cutànea se realice con un buen almohadillado y para ello utilizamos colgajos fasciocutaneos, musculares y miocutáneos. Consideramos que los cuidados pre y postoperatorios son de suma importancia para la obtención de resultados satisfactorios. El índice de complicaciones fue del 27%, pero las recidivas no sobrepasaron el 10 %. Como consecuencia de todo ello la estancia media hospitalaria por enfermo intervenido se ha reducido considerablemente (AU)


We describe the surgical treatment that we realice to the Enis-Sarmiento grade III-IV pressure ulcers in spinal cord injury, and the preoperative and postoperative cares acoording to Barcelona´s Guttmann Institute protocols. We review Fifty-nine patients with a good common health and Enis-Sarmiento grade III-IV pressure ulcer operated on before in several occasions. The excision was practised in all the cases with “Guttmann´s pseudo tumor’s technique. A propper cushioning for the covering is essential. That´s why we have used fascicutaneous, muscular and myocutaneous flaps. The pre and postoperative cares are really important to obtain satisfactory results. Complications come up in 27% of the cases, but the relapses are less than 7%. As a consequence, the average stay per partient in the hospital, was considerably reduced (AU)

RESUMO

Within cooperative groups of multi-center clinical trials a standardized documentation is a prerequisite for communication and sharing of data. Standardizing documentation systems means standardizing the underlying terminology. The management and consistent application of terminology systems is a difficult and fault-prone task, which should be supported by appropriate software tools. Today, documentation systems for clinical trials are often implemented as so-called Remote-Data-Entry-Systems (RDE-systems). Although there are many commercial systems, which support the development of RDE-systems there is none offering a comprehensive terminological support. Therefore, we developed the software system TERMTrial which consists of a component for the definition and management of terminology systems for cooperative groups of clinical trials and two components for the terminology-based automatic generation of trial databases and terminology-based interactive design of electronic case report forms (eCRFs). TERMTrial combines the advantages of remote data entry with a comprehensive terminological control.

RESUMO

STUDY DESIGN: Case report. OBJECTIVES: A case report of tolerance to intrathecal baclofen therapy (ITB) treated with intrathecal morphine ('baclofen holiday'). SETTING: Institut Guttmann, Neurorehabilitation Hospital of Barcelona, Spain. CASE REPORT: A 30-year-old female patient is described with incomplete paraplegia below T6 on the left side and below T8 on the right side, ASIA B, caused by trauma occurring 12 years previously, in whom an intrathecal system had been implanted for baclofen infusion 10 years ago. The patient showed tolerance to baclofen therapy and was treated with intrathecal morphine infusion for 2 weeks. Baclofen infusion resulted in adequate control of spasticity.
