Preoperative diagnosis of ureteral medial deviations secondary to deep endometriosis using transvaginal ultrasound examinations: Can we predict the need for ureterolysis during laparoscopic surgery?

Objective: To evaluate ureteral involvement using transvaginal sonography (TVS) regarding the distortion of the course of the ureters caused by deep endometriosis (DE), which can facilitate predicting the need for ureterolysis during surgery, even in the absence of ureteral stenosis or dilatation.

Methods: This is a single-center, observational, retrospective pilot study of 88 consecutive patients who later underwent surgery for DE that used ultrasound preoperative diagnosis of ureteral medial deviation of one or both ureters between January 2019 and January 2022. At TVS, the course of the ureter was considered medialized if, in longitudinal and transversal section, any distance was detectable between the ureter and the cervix at the point where the ureter crosses the uterine artery.

Vascular- and nerve-sparing bowel resection for deep endometriosis: A retrospective single-center study.

Objective: Surgical management of bowel endometriosis is still controversial. Recently, many authors have pointed out the potential benefits of preserving the superior rectal artery, thus ensuring better perfusion of the anastomosis. The aim of this study was to evaluate the complication rate and functional outcomes of a bowel resection technique for deep endometriosis (DE) involving a nerve- and vascular-sparing approach.

Are ureterolysis for deep endometriosis really all the same? An anatomical classification proposal for ureterolysis: A single-center experience.

Objective: Ureteral endometriosis has an incidence of 0.1% to 1%. The type of surgery required is either conservative (ureterolysis) or radical treatment, depending on the degree of ureter infiltration.

Comparison among three different serological methods for the detection of equine influenza virus infection.

The equine influenza virus (EIV) H3N8 subtype is responsible for all EIV outbreaks worldwide while the H7N7 subtype is less pathogenic and is considered extinct as it has not been confirmed in outbreaks since 1980. Although EIV is enzootic in Brazil, few reports describe the actual EIV antibody status in the country. The aims of this study were: - to evaluate the efficiency of different serum treatments described by the World Organisation for Animal Health (OIE) and the World Health Organization (WHO) to remove non-specific haemagglutination inhibitors for the haemagglutination inhibition (HI) assay for EIV - to evaluate the presence of EIV antibodies by HI, enzyme-linked immunosorbent assay and agar gel immunodiffusion in 83 non-vaccinated equines from São Paulo State - to evaluate a strategy to better analyse equine sera for EIV antibodies.

Detection of Leishmania infantum DNA in conjunctival swabs of cats by quantitative real-time PCR.

Although some studies have investigated the potential role of cats as a reservoir for Leishmania, their role in the epidemiology of visceral leishmaniasis (VL) is still poorly understood. Molecular diagnostic techniques are an important tool in VL diagnosis, and PCR shows high sensitivity and specificity for Leishmania spp. detection.
