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)

Multirresistência antimicrobiana em cepas de Escherichia coli isoladas de cadelas com piometra / Antimicrobial multi-resistance of Escherichia coli strains isolated from bitches with pyometra

The antimicrobial sensibility of Escherichia coli strains isolated from the uterine content of bitches was evaluated. Fifteen E. coli strains were tested in relation to their susceptibility to different antimicrobials. The results demonstrated 100 percent of resistance to all tested drugs, being a quite conflicting finding compared to other works, which observed variable resistance of those bacteria to different antimicrobials but not the same multi-resistance pattern. The detection of those multi-resistance strains configures a problem, with important implications on the antimicrobial therapy. Therefore, additional investigations for a best characterization and extension of this problem are needed.

Aspectos histopatológicos da adenomiose em úteros bovinos nas diferentes fases do ciclo estral / Histophatological aspects of adenomyosis in bovine uteri in different phases of the estrous cycle

Relacionaram-se as características da adenomiose com as fases do ciclo estral em 61 peças de úteros de bovinos colhidas em matadouros. A adenomiose foi classificada em superficial e profunda. A fase do ciclo estral foi estimada pela morfologia, pela coloração e pela vascularização do corpo lúteo e presença ou não de folículos ovarianos maiores que 8mm. Os animais que estavam em anestro (n=11) apresentaram a menor ocorrência de adenomiose (8,2 por cento), e os que estavam na fase lútea média (n=21), a maior (31,0 por cento). Nas fases lútea inicial (n=13) e folicular (n=16) as ocorrências foram semelhantes, 18,0 e 22,9 por cento, respectivamente. A maior porcentagem de adenomiose profunda ocorreu nas fases lútea inicial e média, 45,0 e 47,4 por cento, respectivamente, e durante o anestro e a fase folicular foram de 20,0 e 14,3 por cento, respectivamente. Os resultados sugerem que a fase do ciclo estral influencia na ocorrência de adenomiose e no grau de infiltração miometrial das glândulas endometriais

The relationship of the adenomyosis characteristics and the phases of the estrus cycle in 61 cows bovine's uteruses collected in slaughterhouses was studied. The adenomyoses were classified as superficial and deep. The morphology, staining and vascularization of the corpus luteum and the presence or not of larger ovarian follicles than 8mm helped to estimate tthe estrus cycle. The cows in anestrus (n=11) showed the least occurrence of adenomyosis (8.2 percent) and the animals in the medium luteal phase (n=21) the largest one(31,0 percent). In the initial luteal phase (n=13) and the follicular phase (n=16) the occurrences of adenomyosis were similar and equals to 18.0 and 22.9 percent, respectively. The largests percentage of deep adenomyosis were found in the initial and in the medium luteal phases, 45.0 and 47.4 percent, respectively, and during the anestrus and the follicular phase they were 20.0 and 14.3 percent, respectively. The data suggest that the cycle phase influences in adenomyosis occurrence and in the degree of miometrial infiltration of the endometrial glands

Estudo clínico e histopatológico da genitália de fêmeas bovinas de corte descartadas após a 3ª Inseminação Artificial / Clinical and histopathologic study of genital system of beef cows slaughtered after third artificial insemination

Os exames clínicos, macroscópico e histopatológico post-mortem e de biópsia uterina revelaram em vinte e uma fêmea bovinas de corte descartadas após a terceira Inseminação Artificial que a principal causa de infertilidade fol a infecção uterina. Outras condições associadas ao complexo metrite/endometrite, tais como cisto folicular, hipoplasia ovariana, corpo lúteo cístico e cérvix sinuosa também foram observados. Houve correspondência entre todos os métodos de diagnóstico empregados. O exame clínico dos animais permitiu diagnosticar 76,19% das causas de infertilidade e 71,42% dos casos de infecção uterina, enquanto o exame macroscópico post-mortem demonstrou 95,23% dessas causas. Por outro lado, a biópsia uterina demonstrou a mesma acurácia para o diagnóstico de infecção uterina demonstrada no exame histopatológico post-mortem.

Twenty-one non-pregnant beef cows after third insemination were submitted to clinicai examination of the reproductive tract, including collection of samples for uterina biopsy. Twenty-four hours later they were slaughtered and macroscopic and microscopic examinations of the genital tract were performed. Uterina infections proved to be the major cause of infertility, also associated to others disturbances, such as cystic ovarian disease, ovarian hypoplasia, cystic corpus luteum and sinuosity of the cervix presented in minar cases. Diagnose obtained through rectal palpation of the genital tract, uterina biopsy and post-mortem histopathologyc showed good conformity. Through rectal palpation accurately diagnosed 71,42% of the cows with uterina ifection and 76,19% of ali abnormalities. The post-mortem macroscopic examination of the genital tract found out 95,23% of the pathologic changes presented. Every samples obtained by uterina biopsy showed to uterina infections, which were later confirmed by the post-mortem histopathologic examination. In conclusion, the main cause of infertility in this group of cows was uterina infections.
