Avance de tuberosidad tibial con heteroimplante óseo para el tratamiento de ruptura de ligamento cruzado anterior en caninos / Advance of tibial tuberosity with bone heteroimplant for previous crossed ligament in canine

RESUMEN Las evaluaciones clínica y radiológica son técnicas que se emplean para el diagnóstico de ruptura de ligamento cruzado anterior (RLCA) y para la evaluación posoperatoria de cirugías correctivas. Se planteó como objetivo describir los resultados posoperatorios de la técnica avance de tuberosidad tibial en caninos con RLCA utilizando hueso de origen bovino conservado en glicerina al 98%. Fueron intervenidos 5 caninos con la patología y sin cambios radiológicos marcados en las columnas óseas relacionadas. El heteroim-plante óseo se cortó a manera de cuña y, para determinar su tamaño, se tuvo en cuenta la medida prequirúrgica que necesitaba la rodilla para alcanzar el ángulo de avance de la cresta tibial. Seguidamente se fijó al receptor local con implantes metálicos (agujas de Kirschner y alambre ortopédico). En el posoperatorio, se evaluaron por 90 días signos clínicos como claudicación, dolor al movimiento flexión-extensión e inflamación, según la circunferencia de la rodilla, y se evaluó por 120 días el ángulo de avance tibial y la radiopacidad del heteroimplante con respecto al hueso circunvecino (tuberosidad tibial y tibia caudal). El estudio estableció que los parámetros clínicos y radiológicos tienen un efecto estadísticamente significativo; sin embargo, la evaluación del ángulo de avance tibial no tiene un efecto significativo entre el paciente y los días posquirúrgicos. Durante el periodo de evaluación el heteroimplante óseo bovino demostró ser efectivo para estabilizar una rodilla con RLCA en caninos.

ABSTRACT The clinical and radiological evaluations are techniques used for the diagnosis of the anterior cruciate ligament rupture (LCAR) and the post-operatory assessment of corrective surgeries. It was proposed as an objective to describe the post-operatory results of the advance technique of tibial tuberosity in canines with LCAR using bovine bone conserved in 98% glycerin. Five canines were intervened and with no other radiological changed in the related bone columns. The bone heteroimplant was cut in a wedge-like manner and for its size it was taken into account the pre-operatory measurement that the knee needed to reach the advancement angle of the tibial crest. Next, the bone implant was fixated to the local receptor with metallic implants (Kirschner needles and orthopedic wire). In the post-op, the canines were evaluated for 90 days for clinical signs such as claudication, pain when flexing and extending and inflammation according to the knee circumference, and for 120 days the advancement angle of the tibia and the radiopacitry of the heteroimplant in relation to the surrounding bone. The trial established that the clinical and radiological parameters have a statistically significant effect; however, the evaluation of the tibial advancement angle does not have a significant effect between the patient and the post-operatory days. During the evaluation period, the heteroimplant bovine bone proved to be effective to stabilize the knee in canines with LCAR.

FRECUENCIA DE LESIONES MACROSCÓPICAS EN PULMONES DE BOVINOS TIPO EXPORTACIÓN FAENADOS EN EL FRIGORÍFICO DEL MUNICIPIO DE MONTERÍA, COLOMBIA / FREQUENCY OF MACROSCOPIC LESIONS IN LUNGS OF SLAUGHTERED CATTLE EXPORT TYPE IN THE SLAUGHTERHOUSE OF MONTERIA, COLOMBIA

Se examinaron los pulmones de 582 bovinos machos tipo exportación, de razas cebuínas y diferentes procedencias, faenados en el frigorífico FrigosinÚ del municipio de Montería (Córdoba, Colombia), con la finalidad de identificar las lesiones encontradas en este órgano. El muestreo se hizo en forma sistemática durante 10 días, evaluando animales escogidos al azar. Durante el tiempo de estudio se decomisaron los pulmones de 190 animales (32,6%) con algún tipo de alteración pulmonar mientras el 67,4% no presentó lesiones macroscópicas evidentes. Estos resultados se analizaron mediante estadística descriptiva, encontrándose que el enfisema intersticial fue la causa principal de decomiso en 64,7% de los animales, seguido de hemorragias (15,8%), neumonía lobar (10,5%), congestión pulmonar (8,9%) y broncoaspiración de contenido ruminal (9,0%); sin embargo, el diagnóstico histopatológico no fue contemplado en este estudio y, por lo tanto, el diagnóstico presuntivo se estableció según las lesiones macroscópicas. Se concluyó que la mayoría de las alteraciones encontradas en los pulmones decomisados obedece a fallas en el proceso de insensibilización y sacrificio de los animales, aunque no se pueden descartar problemas infecciosos.

The aim of this study was identify lesions found in lungs in 582 male bovine type export of Zebu breed, from different origins and slaughtered in the refrigerator Frigosinu in the municipality of Montería (Córdoba, Colombia). Sampling was conducted for 10 days systematically and selection of animals for evaluation was made randomly. Results were analyzed using descriptive statistics. During the study, lungs of 190 animals were found with some form of lung lesion, which corresponded to 32.6%. 67.4% of the sampled animals showed no obvious macroscopic alterations. Interstitial emphysema was the main cause of the confiscation, were observed in 64.7% of the animals, followed by hemorrhages (15.8%), lobar pneumonia (10.5%), pulmonary congestion (8.9%) and broncoaspiration of ruminal content (9.0%). However, the histopathologic diagnosis was not done in this study; therefore, presumptive diagnosis according to macroscopic lesions was established. Macroscopic analysis of the lungs evaluated, suggests that most of the alterations found in the lungs was due to flaws in the process of stunning and slaughter of animals, but can not be discard infectious problems in some alterations.

Frecuencia de ptthiosis cutánea en caballos de roducción en explotaciones Ganaaderas de córdoba, Colombia / Frequecy of cutaaneous pythiosis in dairy horses in farms of cordoba, Colomiia

La pythiosis cutánea equina es una enfermedad crónica, granulomatosa, pruriginosa y rápidamente progresiva, que ocurre en regiones con temperaturas que varían de clima templado a caliente (tropical y subtropical) y es causada por el oomiceto Pythium insidiosum. En la Costa Atlántica colombiana, la pythiosis se ve favorecida por las condiciones medioambientales y las inundaciones. El objetivo del presente estudio fue determinar la frecuencia de presentación de pythiosis cutánea en caballos de producción en explotaciones ganaderas del departamento de Córdoba, Colombia. A tal fin, se realizó un estudio descriptivo prospectivo entre los meses de noviembre (2012) y enero (2013); fueron evaluados clínica, epidemiológica e histopatológicamente 47 equinos con lesiones cutáneas granulomatosas compatibles con pythiosis, de un total de 175 equinos pertenecientes a siete explotaciones ganaderas ubicadas en zonas inundables de tres municipios del departamento de Córdoba. La frecuencia de la enfermedad fue de 26,9%. Las manifestaciones clínico-epidemiológicas, las características macroscópicas de las lesiones cutáneas y los hallazgos histopatológicos, indicaron una ocurrencia moderada de pythiosis cutánea en equinos de producción en explotaciones ganaderas de las zonas inundables de dicha zona colombiana.

The equine cutaneous pythiosis is a chronic, granulomatous, often pruriginous, rapidly progressive condition, caused by the oomycete Pythium insidiosum, and with occurrence in regions with temperatures ranging from temperate to hot (tropics and subtropics), as in the Colombian Atlantic Coast, where pythiosis is favored by environmental conditions and floods. The objective of this study was to determine the frequency of occurrence of cutaneous pythiosis in dairy horses of farms of the department of Cordoba, Colombia. We performed a prospective study in animals of convenience, between November of 2012 and January of 2013. We evaluated clinical, epidemiological and histopathologically 47 horses with granulomatous skin lesions compatible with pythiosis, from 175 equine belonging to 7 farms located in flood zones of 3 municipalities of the department of Cordoba, Colombia. The frequency of occurrence of equine cutaneous pythiosis in farms of Cordoba department, was 26.9%. It is concluded that clinical and epidemiological manifestations, macroscopic characteristics of the skin lesions and pathological findings, show a median pythiosis presence of equine dermal in 7 farms located in flood zones of the department of Cordoba, Colombia.

Ocorrência de anticorpos anti-Neospora spp. em jumentos (Equus asinus) no estado de Sucre - Colômbia / Occurrence of anti-Neospora spp. Antibodies in donkeys (Equus asinus) in the state of Sucre - Colombia

A neosporose tem grande importância em bovinos, e sua patogênese neste hospedeiro, em termos gerais, está esclarecida, porém, em equídeos é pobremente conhecida. Na Colômbia ainda não foram reportados anticorpos Anti-Neospora spp. em equídeos, sendo assim objetivou-se no presente estudo avaliar a ocorrência do parasito em jumentos (Equus asinus) de fazendas que apresentavam risco da doença nestes animais. Foram utilizados 56 animais no estado de Sucre (Colômbia), escolhidos aleatoriamente dentro das fazendas selecionadas. Utilizou-se um peptídeo recombinante originado de Neospora caninum (NcGRA1) para o diagnóstico por Dot-ELISA, e o soro foi diluído em 1:200. Este estudo reporta, pela primeira vez no estado de Sucre e na Colômbia, a presença de anticorpos anti-Neospora spp. na espécie Equus asinus, com uma ocorrência de 19,7% (11/56) dos animais amostrados...

The neosporosis has great importance in cattle, and its pathogenesis in this host has been generally clarified, however, in horses, neosporosis is poorly known, and in Colombia anti-Neospora spp antibodies have not been reported. Therefore, the main objective in the present study was to evaluate the occurrence of this parasite in donkeys (Equus asinus) from farms that presented a risk of disease in these animals, as well as no health plan for them. Were used 56 animals randomly chosen inside selected farms in the state of Sucre (Colombia). A recombinant peptide originated from Neospora caninum (NcGRA1) was used for the diagnosis with Dot-ELISA and serum was diluted 1:200. This study is the first to report the presence of anti-Neospora spp. in donkeys (Equus asinus) in the state of Sucre, and in Colombia. The occurrence was in 19.7% of the animals sampled (11/56)...

Descripción clíiica e histopatológica de la rintis micótica granulomatosa en oovinos de córdoba, Colombia / Clinicand histoppathological description of granulomatus fungal rhiniitis in sheep of cordoba, Colombia

El objetivo de este estudio fue describir clínica e histopatológicamente la rinitis micótica granulomatosa causada por Conidiobolus spp. en ovinos del departamento de Córdoba, Colombia. Fueron analizados siete ovinos criollos, hembras, con edades comprendidas entre 2 y 4 años, los cuales recibieron diagnóstico clínico e histopatológico de conidiobolomicosis. Se observaron manifestaciones clínicas similares en todos los ovinos: dificultad respiratoria debido a la obstrucción parcial de los orificios nasales, intolerancia al ejercicio, respiración ruidosa, secreción puro-sanguinolenta bilateral y aumento de volumen de la cavidad nasal. A la necropsia, las cabezas fueron seccionadas longitudinalmente sobre la línea media y se observaron masas de coloración amarillenta irregular con áreas focalizadas de color café oscuro, friable y con coágulos de sangre en la región rinofacial y conchas nasales. En la coloración de H-E, la mucosa de la cavidad nasal presentó necrosis piogranulomatosa multifocal, conteniendo estructuras semejantes a hifas escasamente coloreadas y circundadas por infiltrado de neutrófilos, macrófagos y células gigantes, además de tejido conjuntivo fibroso organizados de forma paralela al rededor del área de necrosis y rodeados por material de Splendore-Hoeppli. En la coloración de Grocott, se observaron hifas irregulares, filamentosas y raramente septadas, cuya morfología es característica de conidiobolomicosis. El diagnóstico se fundamentó en las características clínicas y en los hallazgos histopatológicos, siendo el primer reporte de esta enfermedad en ovinos del departamento de Córdoba y en Colombia.

The objective of this study was to describe clinic and histopathological granulomatous fungal rhinitis caused by Conidiobolusspp. in sheep of the department of Cordoba, Colombia. Seven native sheep were analyzed, females, aged between 2 and 4 years, who were diagnosed clinically with conidiobolomycosis and correlated with histopathological aspects. In describing cases similar clinical manifestations were observed in all animals, difficulty breathing due to partial obstruction of the nostrils, exercise intolerance, noisy breathing, bloody purulent bilateral, similarly showed increased volume of nasal cavity. At necropsy, the heads were sectioned longitudinally on the midline and observed masses of irregular yellowing targeted areas dark brown, friable and blood clots in the nasal region and shells rhinofacial. In the HE stain, the mucosa of the nasal cavity showed multifocal necrosis pyogranulomatous containing hyphae like structures slightly colored and surrounded by infiltration of neutrophils, macrophages and giant cells, and fibrous connective tissue arranged in parallel around the area of necrosis and surrounded by Splendore-Hoeppli material. In the Grocott stain, irregular, filamentous and rarely septate hyphae were observed, suggesting the morphology of the hyphae in the tissue, which is characteristic of conidiobolomycosis. The diagnosis was based on the clinic and histopathological findings, the first report of the disease in sheep of department of Córdoba and Colombia.

A step towards decentralized wastewater management in the Lower Jordan Rift Valley.

In order to address serious concerns over public health, water scarcity and groundwater pollution in Jordan, the expansion of decentralized wastewater treatment and reuse (DWWT&R) systems to small communities is one of the goals defined by the Jordan government in the "Water Strategy 2009-2022". This paper evaluates the general potential of decentralized wastewater system solutions to be applied in a selected area of the Lower Jordan Rift Valley in Jordan. For the study area, the connection degree to sewer systems was calculated as 67% (5% in the rural sector and 75% in the urban sector). The annual wastewater production available for DWWT&R in the rural sector of the investigation area was calculated to be nearly 3.8 million m(3) at the end of 2007. The future need of wastewater treatment and reuse facilities of the rural sector was estimated to be increasing by 0.11 million m(3) year(-1), with an overall potential of new treatment capacity of nearly 15,500 population equivalents (pe) year(-1). The overall potential for implementing DWWT&R systems in the urban sector was estimated as nearly 25 million m(3) of wastewater in 2007. The future need of wastewater treatment and reuse facilities required for the urban sector was estimated to be increasing at a rate of 0.12 million pe year(-1). Together with the decision makers and the stakeholders, a potential map with three regions has been defined: Region 1 with existing central wastewater infrastructure, Region 2 with already planned central infrastructure and Region 3 with the highest potential for implementing DWWT&R systems.

[Neuroepidemiology profile of the central zone of the department of Caldas (Colombia), years 2004-2005]. / Perfil neuroepidemiológico en la zona centro del departamento de Caldas (Colombia), años 2004-2005.

INTRODUCTION: The neurological disease (ND) is a challenge for the medical community, cause of a high degree of morbility, mortality, deterioration in the quality of life of the patient and its family. AIM. To determine the prevalence of ND in the population of the department of Caldas (Colombia): migraine, movement disorders, cerebrovascular diseases, peripheral neuropathy, epilepsy, dementia and insomnia. This last one is innovating aspect in the published Colombian studies has not considered and therefore its prevalence with World Health Organization (WHO) methodology is not known. PATIENTS AND METHODS: This is a population, descriptive study, of cross section. The neuroepidemiological protocol developed by the WHO, modified for Colombia was used. The suspicious cases to suffer ND were evaluated by the neurologist. The information was processed in the statistical package Epi Info 6.04d. RESULTS: Of 787 interviews, 360 were suspicious of ND; additionally 20 non suspicious subjects were evaluated like controls. The global prevalence of ND, excluding insomnia was 13.4%, while including insomnia was 60.4%. The prevalence diseases in sequence (by 1,000 inhabitants) were: insomnia 468 (CI 95%: 433.4-504.4), migraine 278 (CI 95%: 246.3-310.2), dementia (in older 50 years) 51 (CI 95%: 15.8-87), peripheral neuropathy 48 (CI 95%: 32.7-63.4), movement disorders 25 (CI 95%: 13.8-37.0), epilepsy 24 (CI 95%: 12.8-35.5) and cerebrovascular disease 10 (CI 95%: 2.5-17.8). CONCLUSIONS: These results show high prevalence of migraine in our community. Also, the peripheral neuropathy, movement disorders and epilepsy were more frequent than in previous investigations. Dementia and stroke presented prevalence similar to the reported one. The insomnia showed very high prevalence, but by the non possibility of comparison with other local studies, it is need conduced others studies to confirm these findings.
