Articulo originalmente publicado en:Robles C, Chavarria Chavarria M. Presentacion de un caso clinico de cisticercosis cerebral tratado medicamente con un nuevo farmaco: Praziquantel. Salud Publica de Mexico. 1979;XXI:603–18.- - - La cisticercosis es problema grave en los paises latinoamericanos y otros, no ha habido tratamiento medico; la cirugia es satisfactoria en pequeno porcentaje de los enfermos. La experimentacion sobre el tratamiento de la cisticercosis en el cerdo, realizada por Chavarria con Praziquantel demostro que se puede exterminar a los cisticercos alojados en el tejido muscular y en los centros nerviosos. Logrado este objetivo, se planteo con el Dr. Robles la traspolacion de estos resultados al hombre y se aplico el tratamiento a un nino de 6 anos. Primero se cumplieron los requisitos para experimentar en humanos que indica la Carta de Helsinki y se levanto acta con los padres del paciente, sabedores de que se usaria nuevo medicamento veterinario de accion y reacciones desconocidas en humanos. Se aprovecho este caso ya estudiado y con diagnostico elaborado y verificado en varias instituciones; este caso es de cisticercosis intracerebral multiple, diseminada, con lesiones supra e infratentoriales, con pronostico fatal, que esta ampliamente probado por la observacion clinica. El enfermo fue hospitalizado en un centro de reconocida solvencia y con amplios recursos humanos de laboratorio, equipo, etc., para hacer frente a cualquier emergencia. La droga fue administrada por via oral a la dosis de 50 mg/kg de peso en 24 horas durante 15 dias. Para prevenir complicaciones el primer autor (Robles) creyo conveniente administrar prednisona a la dosis diaria y oral de 30 mg durante la realizacion del estudio con muy buenos resultados; tambien se administro fenobarbital a la dosis de 0.05 diariamente. El enfermo era examinado clinicamente todos los dias: signos vitales cada 6 horas; frecuentes determinaciones de biometria hematica, orina, quimica sanguinea, dosificacion de protrombina, determinacion del tiempo de coagulacion y de sangrado; pruebas de funcionamiento hepatico, dosificaciones de bilirrubinas, transaminasas y deshidrogenasa lactica. No hubo ningun fenomeno de intolerancia, tampoco las reacciones alergicas que han sido senaladas. Con el pronostico fatal de esta forma clinica de cisticercosis que diversos medicos anunciaron a la familia y en lo cual coincidiamos, el caso nos parecio ideal para usar por primera vez en el ser humano un medicamento ya probado en voluntarios humanos con resultados de inocuidad y perfecta tolerancia. Habia sido tratado diariamente con 16 mg de Dexametasona y 7 mg de Fenobarbital. El enfermo presentaba desde hacia dos meses violento cuadro de hipertension craneana, cefalea, vomitos, crisis oculogiras a la derecha y crisis convulsivas, diplopia y edema pupilar.

Mammary adenocarcinomas with metastases are more common in dogs than in cats. Their incidence is 1 in every 4,000 cats. In routine veterinary practice, laboratory exams for diagnosis of these neoplasms are nonspecific and scarcely used. Even though invasive procedure, biopsy, and histopathological findings are the gold standards that define the clinical approach, the clinical evaluation, and image assessment lead the way to the proper treatment, especially when surgical intervention is a possibility. This study describes the clinical signs, histopathological aspects, radiological and scintigraphic findings of a cat with mammary adenocarcinoma and metastases evaluated one hour after intravenous administration of 99mTc-thymine. Our focus was not to discuss the pathological aspects of the disease but the Nuclear Medicine role in metastases detection. Metastases, when lesser than 4mm, could go unnoticed by radiological exams, whereas scintigraphy may detect them. Using 99mTc-thymine scintigraphy, we successfully detected unsuspected metastases in the lungs, liver, and right kidney. Early diagnosis is the key to a better rate of survival due to the given treatment and prognostic. Hence, we strongly recommend the use of 99mTc-thymine scintigraphy as a complementary tool for breast cancer diagnosis in veterinary care.

Morphometric characteristics of blood cells were examined in 44 (16 males, 28 females) Bolson tortoises (Gopherus flavomarginatus) in Mapimi, Mexico. Blood samples were drawn from the subcarapacial vein, and smear stains were used to differentiate and measure the diameter and surface area of cells. Mature and polychromatophilic erythrocytes were identified, as well as five types of leukocytes (lymphocytes, heterophils, eosinophils, basophils and monocytes), and thrombocytes. The shape and color of G. flavomarginatus blood cells were similar to those reported for the G. agassizii , and G. polyphemus species. Blood cell sizes fitted related data from other reptile species. The information generated in this study can help monitor the health status of G. flavomarginatus individuals in the wild, thus advancing efforts to protect this endangered species.

The objective was to evaluate the effects of two (2×) vs three (3×) times per day milking on milk production and milk composition in dairy cows. Fourteen scientific papers, containing production data from 16 trials, where dairy cows were milked 2× or 3×, were analysed using meta-analysis with fixed and random-effects with the R statistical program. The degree of heterogeneity and publication bias were measured with the I2 statistic and Begg’s test, respectively. In addition, the meta-regression analysis explored other sources of heterogeneity for the response. The estimated effect size of 2× and 3× milkings was calculated for dry matter intake (DMI), milk production, and milk composition. Dry matter intake, milk production, and milk fat and protein yields showed substantial heterogeneity (I2>50%). Whereas milk fat-percentage had moderate heterogeneity (I2 .05). Cows milked 2× produced less milk (2.23 kg/d), less milk fat (0.06kg/d), and less milk protein (0.05 kg/d). In contrast, the fat percentage was lower (0.07 units) in 3×, compared with 2× milking frequency. There was no effect of milking frequency on DMI and milk protein percentage. In conclusion, milk production and milk fat and protein yields improves as milking frequency increase from 2× to 3× daily, without affecting DMI. The implementation of 3× milking frequency must consider dairy cow management, labor, and milking parlour infrastructure, particular to each dairy farm.

Phenotypic variation in American bullfrogs ( Lithobates catesbeianus ) bred under intensive systems in Mexico: A preliminary report. Veterinaria Mexico OA. 2020;7(1). doi: 10.22201/fmvz.24486760e.2020.1.747 . Commercial bullfrog farming has increased steadily in Mexico from 1925 to satisfy both the national and international markets. However, intensive production systems are still scarce, and there is a need for information to help further advance their development. Therefore, this study aimed to characterize and compare morphometric and physiological traits of bullfrogs bred under intensive culture systems. Three-year-old breeding adults (n = 100) from five farms in three different states, and one-year old juveniles (n = 60) from two of these locations, were used in the study. The scaled mass index (SMI) was calculated by considering body weight and snout-vent length measurements. Hematocrit and white blood cell concentrations were determined in juveniles, and a leukocyte profile was established. Eight linear (based on measurements from photographs of the skull), plus one geometric, variables, were used for morphometric analyses. Results show that the SMI did not vary between localities or gender in juvenile frogs, while differences were found both between sexes (p < 0.026) and between farms (p < 0.001) in adult frogs. Hematocrit and neutrophil concentrations in juvenile individuals also differed between localities. Linear and geometric morphometric analyses in juvenile frogs showed differences between sexes (p < 0.001) and between localities (p < 0.001), the latter suggesting the existence of at least two morphotypes of this species. This study presents relevant information to help advance bullfrog farming in Mexico.

Veterinaria Mexico OA. 2020;7(1). doi: 10.22201/fmvz.24486760e.2020.1.663. The aim of this study was to examine Turkish consumer attitudes towards animal welfare in terms of cognitive, affective and behavioral dimensions, using a bespoke Animal Welfare Attitude Scale (AWAS). An overall consumer attitude was also determined. The Delphi technique was used to establish an item pool to develop a questionnaire for the construction of the AWAS. This questionnaire was later used for data collection. A total of 2295 consumers were surveyed in 14 cities, in the 7 regions of Turkey. Descriptive statistics, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), reliability analysis, Ward's hierarchical clustering method and One-way ANOVA were used to validate the questionnaire, and to analyze data. Results of the EFA allowed for allocation of 42 items collected under 3 dimensions (cognitive, affective and behavioral), that explained 72% of the total variance of the model. This factor structure was subsequently confirmed by a CFA performed on a different sample of 425 consumers. The Cronbach's Alpha coefficient for AWAS was calculated at 0.829. These results confirmed that the developed AWAS had a valid and reliable scale. The questionnaire showed that consumers' attitudes towards animal welfare were more negative at the behavioral dimension, than either at the cognitive or affective dimensions. Consumers in Turkey were ultimately divided into three groups according to their overall attitudes towards animal welfare as impassive, moderate or sensitive. One-third of Turkish consumers placed in the sensitive group, thus emphasizing a potential niche for animal-friendly food marketing in Turkey.

One-third of Turkish consumers placed in the sensitive group, thus emphasizing a potential niche for animal-friendly food marketing in Turkey.","PeriodicalId":49387,"journal":{"name":"Veterinaria Mexico","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2020-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.22201/fmvz.24486760e.2020.1.663","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44694595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cow-calf management practices in Mexico: Reproduction and breeding. Veterinaria Mexico OA. 2020;7(1). doi: 10.22201/fmvz.24486760e.2020.1.839 . Beef cattle breeding has developed in extensive grazing systems in Mexico, concerning the livelihood of over one million families and affecting the use of natural resources. Reproductive efficiency is a major determinant of both the environmental impact of the herd, and the economic viability of the cow-calf production system. However, as reproductive traits have low heritability, reproductive efficiency can be largely influenced by herd management practices. Thus, a questionnaire was administered as personal interviews to 3280 producers, to investigate the prevalence of practices that could directly influence the reproductive outcome of their cattle. Results show that year-round breeding (93%) and natural service by the bull (97.4%) are the most common mating methods. However, only 41% of producers evaluate the breeding soundness of their bulls, and diagnostic testing for specific reproductive diseases of the sires is barely performed in 20% of the farms. The main declared reason for replacing the bull is old age (26.8%), which is followed by to avoid inbreeding (68.4%). Less than 10% of the operations use methods for the synchronization of the estrous cycle, and most farmers breed their heifers for the first time after 2 years of age (73%). Diagnosis of pregnancy is performed in merely 31% of operations, with 23% of the producers declaring to discard non-pregnant cows. Energy or protein feed supplements are provided to the cattle in 63% of the production units, whilst mineral supplements are given in 79% of the farms. Calves are typically weaned between 6 months and a year of age (85%). Only 16% of operations vaccinate against brucellosis and 17.5% against other reproductive diseases (IBR-DVB-VSR and Leptospirosis). The present study showcases a low frequency of adoption of basic reproductive management practices by cow-calf operations in Mexico. Advancement of these practices, as well as implementation and promotion of associated technologies, denotes an area of opportunity to improve the reproductive efficiency of the national herd.
