The canine neuronal ceroid-lipofuscinosis: a review.

The present article gives a survey over the current scientific knowledge of the canine neuronal ceroid-lipofuscinosis (NCL). NCL is a heterogenous group of lysosomal storage diseases in humans and animals. In consequence of a gene mutation, there is an accumulation of ceroid-lipofuscin in neurons, cells of the retina and the skin and other cells. The stored ceroid-lipofuscin in neurons leads to an impaired cell function and subsequently to cell death. Recently, the underlying genetic defect was discovered in several dog breeds. Genetic testing permits an ante mortem diagnosis of the disease, which up to now was only possible with a positive biopsy result. Another advantage is the identification of carrier animals to eliminate the deleterious alleles.

Echinococcus multilocularis Detection in Live Eurasian Beavers (Castor fiber) Using a Combination of Laparoscopy and Abdominal Ultrasound under Field Conditions.

Echinococcus multilocularis is an important pathogenic zoonotic parasite of health concern, though absent in the United Kingdom. Eurasian beavers (Castor fiber) may act as a rare intermediate host, and so unscreened wild caught individuals may pose a potential risk of introducing this parasite to disease-free countries through translocation programs. There is currently no single definitive ante-mortem diagnostic test in intermediate hosts. An effective non-lethal diagnostic, feasible under field condition would be helpful to minimise parasite establishment risk, where indiscriminate culling is to be avoided. This study screened live beavers (captive, n = 18 or wild-trapped in Scotland, n = 12) and beaver cadavers (wild Scotland, n = 4 or Bavaria, n = 11), for the presence of E. multilocularis. Ultrasonography in combination with minimally invasive surgical examination of the abdomen by laparoscopy was viable under field conditions for real-time evaluation in beavers. Laparoscopy alone does not allow the operator to visualize the parenchyma of organs such as the liver, or inside the lumen of the gastrointestinal tract, hence the advantage of its combination with abdominal ultrasonography. All live beavers and Scottish cadavers were largely unremarkable in their haematology and serum biochemistry with no values suspicious for liver pathology or potentially indicative of E. multilocularis infection. This correlated well with ultrasound, laparoscopy, and immunoblotting, which were unremarkable in these individuals. Two wild Bavarian individuals were suspected E. multilocularis positive at post-mortem, through the presence of hepatic cysts. Sensitivity and specificity of a combination of laparoscopy and abdominal ultrasonography in the detection of parasitic liver cyst lesions was 100% in the subset of cadavers (95%Confidence Intervals 34.24-100%, and 86.7-100% respectively). For abdominal ultrasonography alone sensitivity was only 50% (95%CI 9.5-90.6%), with specificity being 100% (95%CI 79.2-100%). For laparoscopy alone sensitivity was 100% (95% CI 34.2-100%), with specificity also being 100% (95% CI 77.2-100%). Further immunoblotting, PCR and histopathological examination revealed one individual positive for E. multilocularis, whilst the other individual was positive for Taenia martis.

Smaller but denser: postmortem changes alter the CT characteristics of subdural hematomas

PURPOSE The aim of this study was to investigate if (1) the volume of subdural hematomas (SDH), midline shift, and CT density of subdural hematomas are altered by postmortem changes and (2) if these changes are dependent on the postmortem interval (PMI). MATERIALS AND METHODS Ante mortem computed tomography (AMCT) of the head was compared to corresponding postmortem CT (PMCT) in 19 adults with SDH. SDH volume, midline shift, and hematoma density were measured on both AMCT and PMCT and their differences assessed using Wilcoxon-Signed Rank Test. Spearman's Rho Test was used to assess significant correlations between the PMI and the alterations of SDH volume, midline shift, and hematoma density. RESULTS Mean time between last AMCT and PMCT was 109 h, mean PMI was 35 h. On PMCT mean midline displacement was decreased by 57% (p < 0.001); mean SDH volume was decreased by 38% (p < 0.001); and mean hematoma density was increased by 18% (p < 0.001) in comparison to AMCT. There was no correlation between the PMI and the normalization of the midline shift (p = 0.706), the reduction of SDH volume (p = 0.366), or the increase of hematoma density (p = 0.140). CONCLUSIONS This study reveals that normal postmortem changes significantly affect the extent and imaging characteristics of subdural hematoma and may therefore affect the interpretation of these findings on PMCT. Radiologists and forensic pathologists who use PMCT must be aware of these phenomena in order to correctly interpret PMCT findings in cases of subdural hemorrhages.

A simulation study on the statistical monitoring of condemnation rates from slaughterhouses for syndromic surveillance: an evaluation based on Swiss data

Syndromic surveillance (SyS) systems currently exploit various sources of health-related data, most of which are collected for purposes other than surveillance (e.g. economic). Several European SyS systems use data collected during meat inspection for syndromic surveillance of animal health, as some diseases may be more easily detected post-mortem than at their point of origin or during the ante-mortem inspection upon arrival at the slaughterhouse. In this paper we use simulation to evaluate the performance of a quasi-Poisson regression (also known as an improved Farrington) algorithm for the detection of disease outbreaks during post-mortem inspection of slaughtered animals. When parameterizing the algorithm based on the retrospective analyses of 6 years of historic data, the probability of detection was satisfactory for large (range 83-445 cases) outbreaks but poor for small (range 20-177 cases) outbreaks. Varying the amount of historical data used to fit the algorithm can help increasing the probability of detection for small outbreaks. However, while the use of a 0·975 quantile generated a low false-positive rate, in most cases, more than 50% of outbreak cases had already occurred at the time of detection. High variance observed in the whole carcass condemnations time-series, and lack of flexibility in terms of the temporal distribution of simulated outbreaks resulting from low reporting frequency (monthly), constitute major challenges for early detection of outbreaks in the livestock population based on meat inspection data. Reporting frequency should be increased in the future to improve timeliness of the SyS system while increased sensitivity may be achieved by integrating meat inspection data into a multivariate system simultaneously evaluating multiple sources of data on livestock health.

A importância do DNA na Medicina Dentária Forense

Com o presente trabalho pretende-se discutir a importância do DNA na resolução de casos de investigação forense. O Homem, desde os tempos mais remotos tem revelado interesse na confirmação da identidade dos seus semelhantes, pelo desenvolvimento e prática de diversas técnicas de identificação. A partir de uma revisão da literatura, fez-se o estudo dos métodos de identificação humana, sendo este mais aprofundado no que diz respeito ao DNA. Frequentemente são encontrados corpos em que a única peça disponível para o processo de identificação é o dente. As peças dentárias são as estruturas mais resistentes e estáveis do corpo humano, mantendo as suas características e propriedades por longos períodos de tempo pós-morte. A análise do DNA contribui de forma muito importante para os processos de reconhecimento humano, principalmente em casos em que outros métodos de identificação falham devido a decomposição, fragmentação, incineração ou inexistência de dados comparativos ante-morte. Para a obtenção de um perfil genético é necessário executar as seguintes etapas: extração do DNA, sua quantificação e amplificação seguida de análise de determinadas regiões do genoma. Nos dias de hoje, muitos casos de identificação necessitam de uma abordagem multidisciplinar, isto porque em algumas situações existe falta de material padrão ou, por outro lado, pode haver mais do que uma evidência a ser examinada.

Recommended reporting standards for test accuracy studies of infectious diseases of finfish, amphibians, molluscs and crustaceans: the STRADAS-aquatic checklist

Complete and transparent reporting of key elements of diagnostic accuracy studies for infectious diseases in cultured and wild aquatic animals benefits end-users of these tests, enabling the rational design of surveillance programs, the assessment of test results from clinical cases and comparisons of diagnostic test performance. Based on deficiencies in the Standards for Reporting of Diagnostic Accuracy (STARD) guidelines identified in a prior finfish study (Gardner et al. 2014), we adapted the Standards for Reporting of Animal Diagnostic Accuracy Studies—paratuberculosis (STRADAS-paraTB) checklist of 25 reporting items to increase their relevance to finfish, amphibians, molluscs, and crustaceans and provided examples and explanations for each item. The checklist, known as STRADAS-aquatic, was developed and refined by an expert group of 14 transdisciplinary scientists with experience in test evaluation studies using field and experimental samples, in operation of reference laboratories for aquatic animal pathogens, and in development of international aquatic animal health policy. The main changes to the STRADAS-paraTB checklist were to nomenclature related to the species, the addition of guidelines for experimental challenge studies, and the designation of some items as relevant only to experimental studies and ante-mortem tests. We believe that adoption of these guidelines will improve reporting of primary studies of test accuracy for aquatic animal diseases and facilitate assessment of their fitness-for-purpose. Given the importance of diagnostic tests to underpin the Sanitary and Phytosanitary agreement of the World Trade Organization, the principles outlined in this paper should be applied to other World Organisation for Animal Health (OIE)-relevant species.

Incidence and Pattern of Pneumonia in Goats Slaughtered at the Kumasi Abattoir, Ghana

This study aimed at determining the incidence and pattern of pneumonia, in slaughtered goats in Kumasi abattoir, Ghana. One thousand three hundred and fifty lungs of goats; (1,012 Sahelian and 338 West Africa Dwarf goats (WAD) lungs) of different ages (less than a year to above 4 years) were used in this study. The frequency of occurrence of pneumonia, the degree of consolidation as a percentage of the total lung volume and histological assessment were determined by standard techniques. Fifty five (55) lungs (39 Sahelian, 16 WAD goats) were pneumonic (4.07% prevalence). The right lungs had a significant higher average lung consolidation percentage (19.11) while the right cranial lobes were more affected (9.37). WAD goats of 1-2 years are mostly affected with an average percentage consolidation of 11.73% while Sahelian goats above 4 years of age were the most affected with 32.59% consolidation. Does of both breeds were more while Sahelian goats had higher consolidation than other breeds. Histological examination revealed the presence of giant cell, fibrinous and suppurative bronchointerstitial pneumonia suggesting complicated viral pneumonia which was observed to be the most important caprine pneumonia in slaughtered goats in Ghana. Transportation and pregnancy stress were the major contributory factor to the pneumonia observed hence effective ante-mortem examinations will help to minimize the slaughter of pregnant does and transportation stress in Ghana.

Autopsia, embalsamamiento y signos de santidad en el cuerpo de Ignacio de Loyola

Las numerosas biografías que han venido apareciendo en estos últimos años sobre Ignacio de Loyola han abordado en contadas ocasiones el tratamiento post mortem que recibió el cuerpo del santo jesuita. No obstante, aquellas que sí han tratado este capítulo de la vida del Santo, no han tenido presente la riqueza descriptiva e interpretativa que proporciona la Historia de la Medicina. Estos motivos nos han llevado a confeccionar un artículo en el que se pretende reconstruir la manipulación post mortem que recibió su cuerpo. Al mismo tiempo, el presente texto pretende aventurar algunas nociones sobre los profesionales sanitarios que realizaron la autopsia y el posterior embalsamamiento del cadáver, los “signos de santidad” hallados en el organismo y los lugares en los que se conservó el cuerpo del azpeitiarra.

Actitud de los docentes de las facultades de Odontologia Brasilenas ante los aspectos bioeticos, eticos y legales del tratamiento odontológico

The study consist on an analysis of attitude by professors of Brazilian Dental Schools before the aspects bioethical, ethic and legal dental treatment aspects. The data collect occurred by semi-structured questioners send by e-mail and correspondence. It was applied the content analysis, by categorical analysis technique, according to Bardin. About bioethical aspects, 94,6% cited that the decision of treatment should be realized between professional and patient, because it don t interfere on negative form (100%). Everybody consider important the interaction professional/patient, because it establishes the respect and mutual agreement between them (61,8%). Tangent at ethic aspects, 95,5% show all alternatives for determined case, even knowing that can lost patient, explaining on the technique and laical form to clear doubts(61,9%). About legal aspects, 82,4% allege that dental surgeon should treat his patient like consumer whereas offer techniques, materials and know through profession. And, like legal prove on occasional lawsuit, 57,1% mentioned that professional don t need of contract necessarily, but a good documentation about patient and e assigned by him. It concluded that these aspects should be teached always to Dentistry academics, whereas they re inherent at profession, to not stay vulnerable at future ethic, judges and other problems.

Comportamiento agronómico del pasto Cuba CT-115 (Pennisetum purpureum) ante diferentes aplicaciones de Urea 46% en la comarca Cuisalá, Comalapa, Chontales

La producción ganadera tiene como base alimenticia el uso de pastos como el principal insumo. Los productores en su mayoría no disponen de información sobre la calidad y cantidad del alimento suministrado a su ganado. En busca de brindar información sobre el efecto de la fertilización nitrogenada en el pasto Pennisetum purpureum Cuba CT-115, se estableció un experimento en la comarca Cuisalá, Comalapa, Chontales, en el período comprendido de Julio a Diciembre del 2010. Se utilizó un diseño de Bloques Completamente al Azar, los tratamientos evaluados fueron de dosis de kg de nitrógeno ha-1 (0, 100, 200, 300 kg respectivamente). Se realizó un análisis de varianza (Pr<0.05) y se aplicó técnica de separación de medias D.M.S. Las variables evaluadas fueron registradas a los 80 días después del corte de uniformidad, éstas se dividieron en variables de crecimiento, variables productivas y nutricionales. Al aplicar D.M.S a la variable altura de planta, el tratamiento 200 kg presentó el promedio más alto con 190.25 cm, grupo a. El número de yemas encontradas en el mismo tratamiento fue de 9.43 (a). En la producción de MS los tratamientos 200 y 300 kg presentaron los resultados más altos con 109.03 y 104.45 toneladas respectivamente por corte y los porcentajes de proteína encontrados fueron de 7.90 % y 12.33 % para los mismos tratamientos.

Efectividad del método canguro en el tratamiento del dolor en neonatos prematuros y de bajo peso gestacional junto a sacarosa oral en la técnica punción del talón en la Unidad Neonatal.

Durante muchos años se consideró que los neonatos no experimentaban el dolor por su incapacidad para verbalizarlo. Así, concepciones erróneas hicieron que el dolor neonatal no fuese tratado. En la actualidad, existe evidencia científica que corrobora la capacidad para percibir el dolor, siendo necesario su tratamiento. Aun así, el miedo a los posibles efectos secundarios de los fármacos ha obstaculizado el estudio de nuevos fármacos para el tratamiento del dolor. Es por eso que las estrategias no farmacológicas han tomado gran relevancia en el tratamiento de procedimientos dolorosos menores, y como coadyuvantes de los fármacos en procedimientos de mayor intensidad. El método canguro que se define como un contacto piel a piel entre madre e hijo, surgió como una alternativa ante la escasez de incubadoras. Sin embargo, numerosas investigaciones han demostrado los grandes beneficios que aporta, considerándolo también como una medida no farmacológica eficaz en el alivio del dolor neonatal. El objetivo de este estudio es evaluar la efectividad del método canguro junto a la administración de sacarosa oral en la disminución del dolor, en comparación con el procedimiento estándar al realizar la prueba de talón. Para ello, se realizará un ensayo clínico aleatorizado dirigido a los neonatos prematuros y de bajo peso gestacional ingresados en la unidad de neonatal del Hospital universitario de Cruces. La variable principal a estudio es la valoración del dolor medido mediante la escala PIPP. Se compararán los datos recogidos en el grupo control e intervención y el análisis de datos se realizará usando el programa informático SPSS.
