Adenomiose uterina em gata associada à piometra / Uterine adenomyosis in a queen associated to pyometra

Adenomyosis, a non-neoplastic myometrial proliferation, is a rare pathologic condition in domestic animals, of unknown etiology. There is a lack of information about the clinical and pathological features of this disease in cats, therefore just a few reports in that species. The study describes a case of adenomyosis in a feline female. A cat, six years old, undefined breed, not spayed, had abdominal swelling history and vaginal discharge. Clinically, upon abdominal palpation, a diffuse increase suggesting a uterine change was found. The vulva had sanguine-purulent exudates. The choice was for the neutering surgical. Uterine macroscopy revealed cystic endometrial hyperplasia/pyometra in uterine horns, and the presence of a diffuse mass on uterine corpus. Fragments of the mass were sent for histopathological analysis, which revealed adenomyosis of the uterine corpus. The patient exhibited adequate post-operative recovery. The adenomyosis should be considered as a differential diagnosis of uterine neoformation in domestic cats.(AU)

Application of deterministic model of isothermals for population dynamics of Synthesiomyia nudiseta (Diptera, Muscidae)

The isothermal deterministic model adherence was studied to evaluate the population dinamic of Synthesiomyia nudiseta (Diptera, Muscidae). The linear form of equation obtained for the experiments in the several phases, were for Egg: 1/D = -0.18 + 0.02 . T; Larva: 1/D = -0.028 + 0.01. T; Pupa: 1/D = -0.069 + 0.01 . T; and Adult: 1/D = -0.4178 + 0.02 . T. In function of temperature, S. nudiseta can present from 4.18 to 8.95 and from 4.91 to 8.99 generations per year, when calculated through the equations of development and through the simulations, respectively. And the higher the temperature the larger the generation number. Through variance analysis it was verified the significance for the regression equations in relation to the annual generation number (Ng/year) of S. nudiseta in function of the isothermals, for two studied situations. It was obtained a significance of 0,1 percent. The regression equations obtained for these situations were: Ng/year = 5.4 + 0.5 . T and Ng/year = 5.1 + 0.52 . T. The number of generations of S. nudiseta varies linearly with the isothermal. Besides that, the number of annual generations for each isothermal does not differ statistically when calculated through the development equations or through the simulations. Such conditions suggest the adaptation of the deterministic model adopted
