Fibroma uterino en una hembra canina cruzada de 12 años en Veterinaria Vida, Noviembre Managua, Nicaragua 2013

Se analizó un estudio de caso atendido en la Clínica “VIDA ” el 21 de noviembre del 2013. Inicialmente se procedió a la valoración de su estado físico y de salud considerando la edad de la paciente. A partir de la inspección clínica y anamnesis se procedió a brindar un diagnóstico de la patología que presentaba, para fundamentar las principales causas y consecuencia que gen eran las patologías reproductivas en la especie canina. El estudio de caso es una investigación cualitativa de tipo participativa, cuya base es la descripción de sucesos ocurridos en un momento determinado el cual consistía en el análisis de un estudio de caso que no pueden duplicarse por las condiciones individuales del sujeto y de su entorno en particular . El paciente era una perra de 12 años , llamada princesa que t enía completo su programa de vacunación y desparasitación. Después del último celo tuvo descargas vaginal es hemorrágicas , durante 6 días el cual alarmó a la dueña, ya que no mostró síntomas característicos de postraciones . Era alimentada con concentrado, su estro era normal . Se le brindó atención ambulatoria y s e le realizaron exámenes clínicos , realizando la anamnesis , sin mostrar dolor a la palpación, no se detectaron masas abdominales, no se realizó exploración vagina l debido a que la paciente no habí a sido incorporada para reproducción. Se determinó como piómetra en diagnostico presu ntivo, aplicándole vit. K p or tres días y al cuarto día una dosis de medroxiprogesterona para detener el sangrado. A l no haber efecto en el sangrado, se optó por la extirpación quirúrgica del útero el cual se real izó sin problemas, encontrándose: cuernos uterinos y útero hiperplásicos , endometrio con fibromas y pequeñas neoplasias. Se identificó neoplasia uterina causada por quistes ováricos, estrés, trastorno psicológico de adaptabilidad a la ausencia de la dueña, creando un desorde n en las estructuras de cascada del sistema endocrino, viéndose afectado por la relació n de la edad de la paciente. Terminada la cirugía se le entregó la mascota a su dueña junto con las indicaciones postoperatoria pero ya en su casa la paciente murió por complicaciones post quirúrgica no identificadas .

Formação de profissionais de saúde no Brasil: uma análise no período de 1991 a 2008

Estudo conduzido com o objetivo de contribuir para o planejamento e implementação de políticas de qualificação profissional no campo da saúde. Foram analisados 14 cursos de graduação da área da saúde: biomedicina, ciências biológicas, educação física, enfermagem, farmácia, fisioterapia, fonoaudiologia, medicina, medicina veterinária, nutrição, odontologia, psicologia, serviço social e terapia ocupacional, no período de 1991 a 2008. Dados sobre número de ingressantes, taxa de ocupação de vagas, distribuição de concluintes por habitante, gênero e renda familiar foram coletados a partir dos bancos do Ministério da Educação. Para o curso de medicina, a relação foi de 40 candidatos por vaga nas instituições públicas contra 10 nas privadas. A maioria dos ingressantes era composta por mulheres. A região Sudeste concentrou 57% dos concluintes, corroborando o desequilíbrio de distribuição regional das oportunidades de formação de profissionais de saúde e indicando a necessidade de políticas de incentivo à redução dessas desigualdades.

Uso de sistemas de informação geográfica em campanhas de vacinação contra a raiva

OBJETIVO: Desenvolver método para planejamento e avaliação de campanhas de vacinação contra a raiva animal. MÉTODOS: O desenvolvimento da metodologia baseou-se em sistemas de informação geográfica para estimar a população e a densidade animal (canina e felina) por setores censitários e subprefeituras do município de São Paulo, em 2002. O número de postos de vacinação foi estimado para atingir uma dada cobertura vacinal. Foram utilizadas uma base de dados censitários para a população humana, e estimativas para razões cão:habitante e gato:habitante. RESULTADOS: Os números estimados foram de 1.490.500 cães e 226.954 gatos em São Paulo, uma densidade populacional de 1.138,14 animais domiciliados por km². Foram vacinados, na campanha de 2002, 926.462 animais, garantindo uma cobertura vacinal de 54%. O número total estimado de postos no município para atingir uma cobertura vacinal de 70%, vacinando em média 700 animais por posto foi de 1.729. Estas estimativas foram apresentadas em mapas de densidade animal, segundo setores censitários e subprefeituras. CONCLUSÕES: A metodologia desenvolvida pode ser aplicada de forma sistemática no planejamento e no acompanhamento das campanhas de vacinação contra a raiva, permitindo que sejam identificadas áreas de cobertura vacinal crítica.

Herbage accumulation, growth and structural characteristics of Mombasa grass (Panicum maximum Jacq.) harvested at different cutting intervals

The objective of the present study was to evaluate herbage accumulation, morphological composition, growth rate and structural characteristics in Mombasa grass swards subject to different cutting intervals (3, 5 and 7 wk) during the rainy and dry seasons of the year. Treatments were assigned to experimental units (17.5 m(2)) according to a complete randomised block design, with four replicates. Herbage accumulation was greater in the rainy than in the dry season (83 and 17%, respectively). Herbage accumulation (24,300 kg DM ha(-1)), average growth rate (140 kg DM ha(-1) d(-1)) and sward height (111 cm) were highest in the 7 wk cutting interval, but leaf proportion (56%), leaf:stem (1.6) and leaf:non leaf (1.3) ratios decreased. Herbage accumulation, morphological composition and sward structure of Mombasa grass sward may be manipulated through defoliation frequency. The highest leaf proportion was recorded in the 3-wk cutting interval. Longer cutting intervals affected negatively sward structure, with potential negative effects on utilization efficiency, animal intake and performance.

Tumor slices as a model to evaluate doxorubicin in vitro treatment and expression of trios of genes PRSS11, MTSS1, CLPTM1 and PRSS11, MTSS1, SMYD2 in canine mammary gland cancer

Background: In women with breast cancer submitted to neoadjuvant chemotherapy based in doxorubicin, tumor expression of groups of three genes (PRSS11, MTSS1, CLPTM1 and PRSS11, MTSS1, SMYD2) have classified them as responsive or resistant. We have investigated whether expression of these trios of genes could predict mammary carcinoma response in dogs and whether tumor slices, which maintain epithelial-mesenchymal interactions, could be used to evaluate drug response in vitro. Methods: Tumors from 38 dogs were sliced and cultured with or without doxorubicin 1 mu M for 24 h. Tumor cells were counted by two observers to establish a percentage variation in cell number, between slices. Based on these results, a reduction in cell number between treated and control samples >= 21.7%, arbitrarily classified samples, as drug responsive. Tumor expression of PRSS11, MTSS1, CLPTM1 and SMYD2, was evaluated by real time PCR. Relative expression results were then transformed to their natural logarithm values, which were spatially disposed according to the expression of trios of genes, comprising PRSS11, MTSS1, CLPTM1 and PRSS11, MTSS1, SMYD2. Fisher linear discrimination test was used to generate a separation plane between responsive and non-responsive tumors. Results: Culture of tumor slices for 24 h was feasible. Nine samples were considered responsive and 29 non-responsive to doxorubicin, considering the pre-established cut-off value of cell number reduction = 21.7%, between doxorubicin treated and control samples. Relative gene expression was evaluated and tumor samples were then spatially distributed according to the expression of the trios of genes: PRSS11, MTSS1, CLPTM1 and PRSS11, MTSS1, SMYD2. A separation plane was generated. However, no clear separation between responsive and non-responsive samples could be observed. Conclusion: Three-dimensional distribution of samples according to the expression of the trios of genes PRSS11, MTSS1, CLPTM1 and PRSS11, MTSS1, SMYD2 could not predict doxorubicin in vitro responsiveness. Short term culture of mammary gland cancer slices may be an interesting model to evaluate chemotherapy activity.

Mesenchymal progenitor cells from canine fetal tissues: yolk sac, liver, and bone marrow

During fetal development, mesenchymal progenitor (MP) cells are co-localized in major hematopoietic territories, such as yolk sac (YS), bone marrow (BM), liver (LV), and others. Studies using mouse and human MP cells isolated from fetus have shown that these cells are very similar but not identical to adult mesenchymal stem cells (MSC). Their differentiation potential is usually restricted to production of highly committed osteogenic and chondrogenic precursors. Such properties of fetal MP cells can be very useful for tissue regeneration, when a great number of committed precursors are required. The objectives of this study were to isolate and characterize MP cells from canine YS, BM, and LV in early and late stages of fetal development. Gestational stage was identified, and cell culture conditions were evaluated for efficient isolation of canine MP cells. All canine fetal MP cells expressed vimentin, nestin, and CD44 proteins. Cytokeratin 18 expression was observed in BM-and LV-MP cells, and vascular endothelial (VE)-cadherin expression was observed only in YS-MP cells. A small number of MP cells (5%) from LV and YS expressed Oct3/4 protein. The differentiation potential of canine fetal MP cells varied significantly: YS- and BM-MP cells differentiated into bone and cartilage, whereas LV-MP cells differentiation was limited to osteogenic fate. None of the canine fetal MP cells were able to differentiate into adipose cells. Our data suggest that canine fetal MP cells are an appropriate in vitro model to study MP biology from hematopoietic territories and they are a source of committed osteogenic and chondrogenic precursors for regenerative medicine.

PREVALENCE OF ANTIBODIES TO TRYPANOSOMA CRUZI, LEISHMANIA INFANTUM, ENCEPHALITOZOON CUNICULI, SARCOCYSTIS NEURONA, AND NEOSPORA CANINUM IN CAPYBARA, HYDROCHOERUS HYDROCHAERIS, FROM SAO PAULO STATE, BRAZIL

Little is known about the importance of capybara. Hydrochoerus hydrochaeris, as reservoirs for parasites of zoonotic or veterinary importance. Sera from 63 capybaras, from 6 counties in the state of Sao Paulo, Brazil, were examined for antibodies to Trypanosoma cruel, Leishmania infantum, Encephalitozoon cuniculi. Sarcacystis neurona, and Neospora caninum using an indirect immunofluorescent antibody test. Five (8%) of the 63 capybaras had antibodies to T cruzi epimastigotes. None of the samples from capybara reacted positively with L. infantum promastigotes or with spores of E. cuniculi. Two (3%) of the serum samples were positive for antibodies to S. neurona merozoites, and 2 (3%) of the serum samples were positive for antibodies to N. caninum tachyzoites. A serum sample from 1 capybara was positive for antibodies to both T cruzi and N. caninum. None of the remaining 62 samples reacted with more than 1 parasite.

Nuclear morphometry in cytopathology: a prognostic indicator for canine cutaneous mast cell tumors

Twenty-nine canine cutaneous mast cell tumors (MCTs) were morphometrically analyzed with regard to mean nuclear area (MNA) using cytopathology smears. The results showed a correlation between MNA and survival. When graded into 2 morphometrically different groups, there were statistically significant differences among high- and low-grade MCTs, regarding both Romanowsky-type stain and hematoxylin and eosin. Cytomorphometry could also separate histologic grade II tumors with better prognosis from the more aggressive MCTs. The results indicated that nuclear morphometry on cytopathology preparations can predict the biological behavior of cutaneous MCTs in dogs in an independent manner, yielding a rapid and reproducible diagnosis, which renders the method useful for veterinary oncology.

Massive infestation by Perulernaea gamitanae (Crustacea: Cyclopoida: Lernaidae) in juvenile gamitana, cultured in the Peruvian Amazon

The gamitana is a species of socio-economic importance in the Peruvian Amazon, often intensively produced locally for human consumption. Because of this, more studies concerning parasite populations affecting this species culture are necessary. In this study, a heavy copepod infestation of Perulernaea gamitanae is reported in a managed culture of gamitana. The prevalence of infection was 100% and mortality of the fish population was complete. The average intensity and abundance of the parasite was 268.8 parasites per individual.
