Objectives: The objective of this study was to evaluate the diagnostic accuracy of saline infusion hysterosonography for detection of uterine cavity abnormalities using Hysteroscopy as the gold standard. Study Design: Analytical Quasi Experimental study. Setting: Obstetric and Gynaecology Department Madina Teaching Hospital Faisalabad. Period: July 2017 to December 2017. Materials and Methods: Sixty patients presented with abnormal uterine bleeding were included in the study. Transvaginal ultrasound, SIS and hysteroscopy performed for evaluation of the uterine cavity for any abnormality. Results: SIS helped in detection of intacavitary abnormalities in 39 out of 60 patients indicating sensitivity of 88. 64 % and specificity of 100 % as hysteroscopy confirm the findings in all the patients. The NPV is 76 % and PPV of 100 % taking hysteroscopy as gold standard. The diagnostic accuracy of saline infusion sonography is 91%. Conclusion: The addition of SIS to TVS significantly improved the sensitivity and specificity for detecting intracavitary pathology. It can be used as an alternative procedure whenever hysteroscopy is not available.

Abstract Introduction Various forms of female infertility were associated with congenital uterine anomalies and acquired uterine disease. In fact, the myometrium can only be indirectly imaged by X-ray hysterosalpingography but is directly seen on Ultrasonography. More recently, further advances in ultrasonography have led to three-dimensional multiplanar or volume imaging (three-dimensional ultrasonography [3DUS]) in which sonographic images are obtained from a volume of ultrasonographic data (rather than from a slice of data) the application of 3DUS to gynecologic imaging has suggested a role for transvaginal 3DUS in the assessment of uterine anomalies and endometrial lesions. Aim To evaluate the diagnostic accuracy and sensitivity of Hysteroscopy vs TV3D in the evaluation of the uterine abnormalities in infertile women before ICSI. Methodology This is a study including 60 patients were selected from the outpatient gynecological clinic, private center at Sohag government (Ibn Sina Center) in collaboration with (Ain Shams University Hospital in IVF unit) from12/2017 -8/2018. All cases files are computerized and saved in Ibn Sina Center. Results The overall result of accuracy of different modalities was 98.3% for 3D sonography and the accuracy of different modalities in detection of endometrial polyp was 93.3% for 3D sonography and 100% for hysteroscopy. The accuracy of different modalities in detection of septate uterus was 100% for 3D sonography and hysteroscopy. The accuracy of different modalities in detection of intrauterine adhesions was 100% for 100% for 3D and hysteroscopy. Conclusion Hysteroscopy is the gold standard diagnostic & therapeutic tool for uterine anomalies (bicornuate, septate, arcuate, polyp), However 3D ultrasonography is diagnostic tool only but superior to hysteroscopy in certain lesions e.g. (subserous and intramural fibroid). Recommendation we recommend 3D to become soon as the diagnostic procedure of choice in assessment of suspected uterine lesions. Furthermore, we recommend that 3D US, if available, to be performed routinely for all cases of uterine cavity anomalies and prior to corrective uterine surgery.

Aim: The aim of this meta-analysis is to evaluate the diagnostic accuracy of three-dimensional transvaginal ultrasound subjective assessment (3D-TVS) in the preoperative detection of deep myometrial invasion (MI) in patients with endometrial cancer, using definitive frozen section diagnosis after surgery as the reference standard. Material and methods: A search for studies evaluating the role of 3D-TVS for assessing myometrial invasion in endometrial cancer from January 1990 to Novem-ber 2020 was performed in PubMed/MEDLINE and Web of Science. The Quality Assessment of Diagnostic Accuracy Studies 2 evaluated the quality of the studies (QUADAS-2). All analyses were performed using MIDAS and METANDI commands. Results: Nine studies comprising 581 women were included. The mean prevalence of deep MI was 39.8%. QUADAS as-sessment showed that most studies had a high risk for the patient selection domain. Overall, the pooled estimated sensitivity, specificity, positive likelihood and negative likelihood ratio of 3D-TVS for detecting deep MI were 84% (95% CI, 73-90%), 82% (95% CI, 75-88%), 5 (95% CI, 3.1-7.1) and 0.20 95% CI, 0.11-0.35). respectively. Conclusions: 3D-TVS has an accept-able diagnostic performance for detecting MI in women with endometrial cancer.

<b><i>Objective:</i></b> The use of three-dimensional (3D) transvaginal ultrasonography (TVS) has been investigated for the diagnosis of deep endometriosis (DE). This study aimed to evaluate if 3D reconstructions improve the performance of TVS) in assessing the presence and characteristics of bladder endometriosis (BE). <b><i>Design:</i></b> This was a single-center comparative diagnostic accuracy study. <b><i>Participants/Materials, Setting, Methods:</i></b> Patients referred to our institution (Piazza della Vittoria 14 Srl, Genova, Italy) with clinical suspicion of DE were included. In case of surgery, women underwent systematic preoperative ultrasonographic imaging; an experienced sonographer performed a conventional TVS; another experienced sonographer, blinded to results of the previous exam, performed TVS, with the addition of 3D modality. The presence and characteristics of BE nodules were described in accord with International DE Analysis group consensus. Ultrasound data were compared with surgical and histological results. <b><i>Results:</i></b> Overall, BE was intraoperatively found in 34 out of 194 women who underwent surgery for DE (17.5%; 95% confidence interval: 12.8–23.5%). TVS without and with 3D reconstructions were able to detect endometriotic BE in 82.2% (<i>n</i> = 28/34) and 85.3% (<i>n</i> = 29/34) of the cases (<i>p</i> = 0.125). Both the exams similarly estimated the largest diameter of BE (<i>p</i> = 0.652) and the distance between the endometriotic nodule and the closest ureteral meatus (<i>p</i> = 0.341). However, TVS with 3D reconstructions was more precise in estimating the volume of BE (<i>p</i> = 0.031). In one case (2.9%), TVS without and with 3D reconstructions detected the infiltration of the intramural ureter, which was confirmed at surgery and required laparoscopic ureterovesical reimplantation. <b><i>Limitations:</i></b> The extensive experience of the gynecologists performing the ultrasonographic scans, the lack of prestudy power analysis, and the population selected, which may have been influenced by the position of the institution as a referral center specialized in the treatment of severe endometriosis, are limitations of the current study. <b><i>Conclusion:</i></b> Our results demonstrated the high accuracy of ultrasound for diagnosing BE. The addition of 3D reconstructions does not improve the performance of TVS in diagnosing the presence and characteristics of BE. However, the volume of BE may be more precisely assessed by 3D ultrasound.

Hindlimb Lameness

Visual equine lameness assessment is often unreliable, yet the full understanding of this issue is missing. Here, we investigate visual lameness assessment using near-realistic, three-dimensional horse animations presenting with 0–60 per cent movement asymmetry. Animations were scored at an equine veterinary seminar by attendees with various expertise levels. Results showed that years of experience and exposure to a low, medium or high case load had no significant effect on correct assessment of lame (P>0.149) or sound horses (P≥0.412), with the exception of a significant effect of case load exposure on forelimb lameness assessment at 60 per cent asymmetry (P=0.014). The correct classification of sound horses as sound was significantly (P<0.001) higher for forelimb (average 72 per cent correct) than for hindlimb lameness assessment (average 28 per cent correct): participants often saw hindlimb lameness where there was none. For subtle lameness, errors often resulted from not noticing forelimb lameness and from classifying the incorrect limb as lame for hindlimb lameness. Diagnostic accuracy was at or below chance level for some metrics. Rater confidence was not associated with performance. Visual gait assessment may overall be unlikely to reliably differentiate between sound and mildly lame horses irrespective of an assessor’s background.
