Endometrite fúngica em éguas: diagnóstico e implicações clínico-patológicas / Fungal endometritis in mares: diagnosis and clinicopathological aspects

Este estudo objetivou estabelecer a etiologia e achados clínico-patológicos das endometrites fúngicas. Para tal, realizou-se anamnese, exame ginecológico, cultura, citologia e biópsia endometriais em 85 éguas em idade reprodutiva e que não pariam havia um ano ou mais. Das 85 éguas, 24 (28%) apresentaram exames compatíveis com endometrite infecciosa. Destas, em 20% (5/24), confirmou-se endometrite com envolvimento fúngico. Os fungos isolados foram: Candida guilliermondii, C. tropicalis, C. pseudotropicalis associadas ao Bacillus sp. em uma égua; C. albicans em duas fêmeas (uma associada a Escherichia coli); um caso de Trichosporon penicillatum e um de T. capitatum. Todos animais diagnosticados com endometrite fúngica apresentaram inflamações endometriais moderadas, nos exames de citologia e no histopatológico, sendo estes achados compatíveis com o histórico e o exame reprodutivo destes animais. Destacou-se a presença constante de linfócitos e plasmócitos nos dois exames, assim como das lesões degenerativas no endométrio através da biópsia endometrial. Em 80% (4/5) constataram-se estruturas fúngicas na citologia endometrial, porém no exame histopatológico, não foi possível detectar tais estruturas. Após o estudo pode-se afirmar que a metodologia utilizada foi eficiente para diagnosticar a endometrite fúngica, com destaque para o exame de citologia endometrial, e que este tipo de endometrite teve caráter crônico em todos os animais.

The aim of the present study was to determine the causes and clinical findings of endometritis. The history, reproductive examination and endometrials culture, uterine cytology and biopsy from 85 mares in reproductive age that did not foal a year or more were performed. Twenty four (28%) out of 85 mares had signals compatible with infectious endometritis. From those, 20% (5/24) had fungal involvement, and the agents were: Candida guilliermondii, C. tropicalis, C. pseudotropicalis, in association to Bacillus sp. in one mare; two mares had C. albicans, and one of them associated with Escherichia coli; a case of Trichosporon penicillatum and another of T. capitatum. All animals with fungal endometritis presented moderate endometrial inflammation, at cytology and uterine biopsy, which was compatible with the animal's history and reproductive exam. The endometrial cytology and biopsy revealed numerous lymphocytes and plasmocytes as well as the degenerative lesions in the endometrial biopsy. Fungal structures were presented at the endometrial cytology smears in 80% (4/5) of the mares, however those structures were not detected in the biopsy. In conclusion, the methodology used was efficient to diagnose fungal endometritis, with standing for the examination of endometrial cytology, and the fungal endometritis had chronic character in all animals.

Dinâmica da involução uterina no pós-parto de vacas da raça Guzerá / Dynamics of the uterine involution in postpartum guzerá cows

Com o objetivo de avaliar o processo fisiológico da dinâmica de involução uterina em vacas da raça Guzerá, foram acompanhadas 19 vacas adultas no puerpério fisiológico em seis momentos, no parto e 7, 14, 21, 28 e 42 dias pós-parto (dpp), avaliando os parâmetros vitais, escore de condição corporal, exame ginecológico, avaliação ultrassonográfica e características e odor da secreção vaginal. Aos 42 dpp realizou-se a citologia endometrial pela técnica de cytobrush. Observou-se que aos 21 dpp, 100% das vacas apresentavam o útero na cavidade pélvica e tamanho compatível ao do órgão normal. Aos 42 dpp as vacas apresentaram 42,1% de taxa de ciclicidade e não apresentavam endometrite citológica, o menor resultado encontrado na literatura para raças de bovinos de corte.

The objective was to characterize the dynamic of physiological process of uterine involution in Guzerá cows. Nineteen cows were accompanied in physiological postpartum period, in six moments, partum and 7, 14, 21, 28 and 42 days in milk (DIM), which were evaluated the vital parameters, body condition score, gynecological examination, ultrasound assessment and evaluation of characteristics and odor of vaginal discharge. It was also collected samples for endometrial cytology by a cytobrush technique at 42 DIM. It was observed that at 21 DIM, showed 100% of the uterine up in the pelvic cavity, with a size compatible to the normal body. Cows didn't have cytological endometritis at 42 DIM, this data is the smallest found in the literature for breeds of beef cattle, and cows had a rate cyclicality of 42.1% at 42 DIM.

Diagnostic test of endometrial cytobrush in cases of perimenopausal and postmenopausal hemorrhage.

Perimenopausal menopausal hemorrhage can be due to by a variety of causative factors. One of its dangerous causes is atypical hyperplasia and endometrial carcinoma. There are a number of risk factors for the occurrence of endometrial carcinoma. The group that has this risk belongs to high-risk group. In this high-risk group, it is necessary to have a method to identify the changes in endometrial abnormality. One of the alternatives is the examination of endometrial cytology. The objective of this study was to evaluate the sensitivity, specificity and correlation test between endometrial cytology and endometrial histology. This study was a diagnostic test of cytological examination of the endometrium as compared with endometrial histology. Endometrial cytology was performed with a modification of cytubrush and IUD shell. Specimen was dissolved into the centrifuged NaCl, and its deposits were then processed for cytological examination with Papanicolaou and Giemsa staining. After the taking of cytology, the process was continued with curettage of the endometrium, and the specimens were processed for cytological examination. Both of them were examined by anatomic pathologist. Statistical analysis used diagnostic test using histological examination of curetage specimens as gold standard. During the period of study 45 study samples were collected, among which 12 (26.66%) were endometrial adenocarcinoma, 6 (13.33%) with atypical hyperplasia, 11 (24.44%) with non-atypical hyperplasia, 15 (33.33%) were samples without abnormality, and one sample with endometritis. Actual correlation value was 57.8%, correlation because of possibility 3.38%, and correlation not because of possibility 54.42%, potential correlation not because of possibility 96.62%, and Kappa value 0.56. It was concluded that cytological examination of the endometriurn with cytobrush could be employed as a screening method in the abnormalities of endometrial thickness, with sensitivity of 62.5% and specificity of 62.2%.
