RESUMO

Müllerian anomalies such as Robert's uterus, which was first described by the French gynaecologist Dr Helene Robert in 1969, are rare clinical entities and have been reported in <3% of the female population. Robert's uterus is a rare phenomenon with a relative dearth of reported cases. Affected individuals may present with pelvic pain and dysmenorrhoea that intensifies near menses or acutely, with severe abdominal pain to the emergency department. They are also associated with adverse pregnancy outcomes, abnormal fetal presentation, preterm labour, recurrent pregnancy loss and infertility. Although ultrasound has a role in its initial assessment, MRI is the best modality to further delineate its anatomy. It is typically managed via laparotomy and total horn resection, endometrectomy of the blind cavity or abdominal metroplasty. The authors present the case of a 40-year-old woman at 19+3 weeks gestation with acute onset of left-sided abdominal pain. A transvaginal ultrasound and MRI of the pelvis confirmed a Robert's uterus with a viable pregnancy in the upper left horn. She developed a ruptured horn with significant haemoperitoneum. An emergency laparotomy was performed and a non-viable fetus was evident. Only a few cases of pregnancy in the blind hemicavity have been reported so far. This case also highlights the importance of considering this diagnosis in young females presenting with dysmenorrhoea and normal menstrual flow. It is imperative to render a prompt diagnosis, as minimally invasive procedures may be more effective if detected before the formation of adnexal endometriomas.

RESUMO

Controversial surgical anatomical landmarks in the deep pelvis can be visualized and identified using current technologies. Performing the gate approach technique during deep lateral dissection for total mesorectal excision facilitates visualization of the pelvic neurovascular structures following simple dissection steps to preserve the pelvic autonomic nerves and avoid accidental vascular injuries. Here, we discuss laparoscopic exposure of an infrequent disposition of the middle rectal artery anterior to the lateral ligament of the rectum while performing the gate approach.

RESUMO

BACKGROUND: We developed a mobile device application and dedicated pelvic positioner with the aim of improving the acetabular cup placement accuracy in patients undergoing total hip arthroplasty (THA). The function of the application was to display the intra-operative cup angle. The accuracy and clinical usefulness of this combined method were verified through comparison with the conventional alignment guide method. METHODS: In total, 60 patients who underwent cementless THA were included in this study. We compared the cup alignment when using this combined method with that when using the conventional alignment guide method. The absolute value error between the intra- and post-operative angles of inclination and anteversion of the cup was calculated. RESULTS: The absolute value error of inclination was 2.4° ± 2.1° in the study group and 4.0° ± 3.3° in the control group (P = 0.107). The absolute value error of anteversion was 2.8° ± 2.6° in the study group and 7.4° ± 5.3° in the control group (P < 0.001). CONCLUSION: Using the application and pelvic positioner is simple and can be introduced at a low cost. The more accurate measurement of the intra-operative cup angle using this combined method has improved the cup insertion accuracy compared with that of the conventional alignment guide method.

RESUMO

CT image based organ segmentation is essential for radiotherapy treatment planning, and it is laborious and time consuming to outline the endangered organs and target areas before making radiation treatment plans. This study proposes a fully automated segmentation method based on fusion convolutional neural network to improve the efficiency of physicians in outlining the endangered organs and target areas. The CT images of 170 postoperative cervical cancer stage IB and IIA patients were selected for network training and automatic outlining of bladder, rectum, femoral head and CTV, and the neural network was used to localize easily distinguishable vessels around the target area to achieve more accurate outlining of CTV.

RESUMO

The human pelvis shows marked sexual dimorphism that stems from the conflicting selective pressures of bipedal locomotion and parturition. The sacrum is thought to reflect this dimorphism as it makes up a significant portion of the pelvic girdle. However, reported sexual classification accuracies vary considerably depending on the method and reference sample (54%-98%). We aim to explore this inconsistency by quantifying sexual dimorphism and sex classification accuracies in a geographically heterogeneous sample by comparing 3D geometric morphometrics with the more commonly employed linear metric and qualitative assessments. Our sample included 164 modern humans from Africa, Europe, Asia, and America. The geometric morphometric analysis was based on 44 landmarks and 56 semilandmarks. Linear dimensions included sacral width, corpus depth and width, and the corresponding indices. The qualitative inspection relied on traditional macroscopic features such as proportions between the corpus of the first sacral vertebrae and the alae, and sagittal and coronal curvature of the sacrum. Classification accuracy was determined using linear discriminant function analysis for the entire sample and for the largest subsamples (i.e., Europeans and Africans). Male and female sacral shapes extensively overlapped in the geometric morphometric investigation, leading to a classification accuracy of 72%. Anteroposterior corpus depth was the most powerful discriminating linear parameter (83%), followed by the corpus-area index (78%). Qualitative inspection yielded lower accuracies (64-76%). Classification accuracy was higher for the Central European subsample and diminished with increasing geographical heterogeneity of the subgroups. Although the sacrum forms an integral part of the birth canal, our results suggest that its sex-related variation is surprisingly low. Morphological variation thus seems to be driven also by other factors, including body size, and sacrum shape is therefore likely under stronger biomechanical rather than obstetric selection.

RESUMO

Sex determination of the human pelvis has traditionally been done through visual analyses of morphoscopic traits and there are limited metric methods available to forensic anthropologists to add metric credibility to these analyses. The goal of this research was to create an improved metric method using three-dimensional geometric morphometrics to determine sex from both whole and modeled fragmented human pubic bones. The sample consisted of n = 378 pubic bones from the University of New Mexico's Maxwell Museum Documented Skeletal Collection and eight landmarks were collected from each bone. Statistical analyses and machine learning algorithms were used to predict the accuracy of the method's ability to classify a bone as male or female on both whole and simulated fragmented remains; this included tests run on each possible landmark combination of three or more landmarks to simulate fragmented bones (218 combinations). The results of the whole bone analysis resulted in 95.35% testing accuracy. The results of the modeled fragmentary analysis consisted of 164 combinations which exhibit a 90% or higher accuracy in sex prediction; and twelve combinations which exhibit 96% or higher accuracy in sex prediction. In particular, two landmarks clustered around the ventral arc of the pubic bone performed the best, indicating this is the most sexually dimorphic portion of the bone. These results indicate that three-dimensional geometric morphometrics is a valid method to be applied to sex determination in forensic anthropology.

RESUMO

The ever-increasing incidence of prostate cancer is driving research and clinicians efforts to manage the disease more precisely. Leaving aside the progress we are making in the field of prostate cancer treatment, we can notice the pressure on accurate diagnosis in everyday practice. We often meet patients who are in the so-called gray zone and we are not sure whether to indicate a prostate biopsy or continue to monitor the patient. For diagnostics, we use a number of more or less proven methods that we have at our disposal. No clinical urologist wants to send their patient for a prostate biopsy unnecessarily. However, if the patient is finally planned for a prostate biopsy, there is no 100% certainty that we will detect the cancer. For this reason, there is an effort to develop other methods that would refine the collection of histological material and thus increase the capture of those patients who need treatment. The aim of this review is to show modern approaches to diagnostics and outline the direction in which diagnostics will go in the coming years.

RESUMO

Human infants are born neurologically immature, potentially owing to conflicting selection pressures between bipedal locomotion and encephalization as suggested by the obstetrical dilemma hypothesis. Australopithecines are ideal for investigating this trade-off, having a bipedally adapted pelvis, yet relatively small brains. Our finite-element birth simulations indicate that rotational birth cannot be inferred from bony morphology alone. Based on a range of pelvic reconstructions and fetal head sizes, our simulations further imply that australopithecines, like humans, gave birth to immature, secondary altricial newborns with head sizes smaller than those predicted for non-human primates of the same body size especially when soft tissue thickness is adequately approximated. We conclude that australopithecines required cooperative breeding to care for their secondary altricial infants. These prerequisites for advanced cognitive development therefore seem to have been corollary to skeletal adaptations for bipedal locomotion that preceded the appearance of the genus Homo and the increase in encephalization.

RESUMO

OBJECTIVE: To evaluate the morphological asymmetry of pelvic rings existing in healthy individuals in terms of three-dimensional (3D) geometric shapes. METHODS: This study was a retrospective self-control study. CT images of healthy pelvises, scanned from Jan 2014 to Jan 2019, were taken from 159 subjects (88 males and 71 females) aged 20 to 59 years (39.1 ± 8.7 years). Digital pelvic ring models were reconstructed from CT images and then flipped over the corresponding sagittal planes to obtain their mirrored models. A 3D deviation analysis of a pelvic ring was conducted between the original model and its mirrored model via model registration and quantification of the geometric differences. Next, the pelvic rings were split to the left and right hipbones. The same flipping procedures as done by pelvic rings were performed for left hipbones to obtain their mirrored models. A 3D deviation analysis was also performed between the left and right hip bones. Quantitative variables representing deviation mainly included the average deviation (AD) and the maximum deviation (MD). MDs over 4 mm and 10 mm were deemed as critical levels for evaluating the severity of asymmetry as per Matta's scoring system. The quantitative assessments of the asymmetry covered pelvic rings, bilateral hip bones and the specific anatomic regions of a hip bone. RESULTS: 157 out of 159 pelvic rings (98.74%) had more than 4 mm of the MD and 27 (16.98%) of them exceeded 10 mm of the MD. The MD of pelvic rings was 1.23 times as high as that for the bilateral hip bones (7.46 mm vs. 6.08 mm, P < 0.05). The ADs of pelvic rings and bilateral hip bones were 1.28 mm and 0.94 mm, respectively (P < 0.05); 2.27% of the surface points of a pelvic ring had more than 4 mm geometric deviations compared with its mirrored model, while 0.59% (P < 0.05) of bilateral hip bones were on the same level of deviation. 119 out of 159 pelvic iliac crests (74.8%) had MDs more than 4 mm, and 15 (9.4%) reached 10 mm or more. Only 15 (9.4%) pelvises presented asymmetric features in the area of obturator foramen where the MDs exceeded 4 mm. CONCLUSIONS: Pelvic asymmetry exists in the general population, but 3D geometric symmetry is present in specific anatomic regions. It implies that restoring the 3D symmetry of specific anatomic regions is more reliable than "restoring the symmetry of pelvic ring" in pelvic ring reduction or pelvic fixation design.

RESUMO

OBJECTIVE: To explore and analyze the change of pelvic sagittal tilt (PST) after total hip arthroplasty (THA) in patients with bilateral Crowe type IV developmental dysplasia of the hip (DDH). METHODS: The study retrospectively evaluated 43 patients with bilateral Crowe type IV DDH undergoing THA from January 2008 to June 2019 who were followed up for 12 months postoperatively. Four parameters, including the ratio between the height and width of the obturator foramina(H/W ratio), the vertical distance between the upper edge of the symphysis and the middle of the sacrococcygeal joint (SSc distance), the vertical distance between the upper edge of the symphysis and the line connecting bilateral hip centers (SC distance) and the vertical distance between the upper edge of the symphysis and the line connecting the bilateral lower ends of the sacroiliac joints (SSi distance), which could indirectly reflect the change of PST, were observed and measured by radiographs. The change of each parameter before operation, immediately after operation, and in 3, 6 and 12 months postoperatively was compared and analyzed. RESULTS: Compared with the value before operation, the H/W ratio immediately after operation and in 3, 6 and 12 months postoperatively were 0.61 ± 0.12 (t = 0.893, P = 0.377), 0.61 ± 0.11 (t = 1.622, P = 0.112), 0.67 ± 0.10 (t = 5.995, P < 0.001) and 0.76 ± 0.12 (t = -9.313, P < 0.001), respectively, and the SSc, SC and SSi distance in 6 months postoperatively were 30.12 ± 7.06 mm (t = 3.506, P = 0.002), 42.8 ± 7.7 mm (t = 5.843, P < 0.001), 129.3 ± 12.6 mm (t = 5.888, P < 0.001), respectively, and in 12 months postoperatively were 27.24 ± 7.68 mm (t = 6.510, P < 0.001), 36.1 ± 9.1 mm (t = 9.230, P < 0.001), 118.9 ± 14.9 mm (t = 8.940, P < 0.001), respectively. The radiographs obtained in 6 and 12 months postoperatively demonstrated a significantly increased H/W ratio and decreased SSc, SC and SSi distance. At the last follow-up, the clinical evaluations significantly improved in all patients and there were no revisions. CONCLUSION: The significant change of pelvic sagittal posterior tilt in patients with bilateral Crowe type IV DDH might be a significant phenomenon after THA, which could occur in 6 months postoperatively.

RESUMO

Background: Treatment of pelvic venous disorders (PVD) including pelvic congestion syndrome (PCS) are often delayed due to its varying clinical manifestations. Patients and methods: Patient referral was based on a literature- and personal experience-derived clinical "PCS screening score" (higher score points indicate greater likelihood with a maximum score of 10 points). We studied consecutive women who were (i) referred for vascular assessment and treatment to the University Hospital Zurich (2017-2021), (ii) had a PCS score ≥3 points, (iii) had evidence of obstructive or non-obstructive PVD by duplex sonography or cross-sectional imaging, and (iv) underwent endovascular therapy. The primary outcome was change in symptom severity after endovascular therapy: (i) freedom from symptoms, (ii) improvement with residual symptoms, (iii) no improvement. Results: We included 43 women (mean age 36 years): 81% had previous pregnancy, 19% endometriosis. The median PCS score was 7 (IQR 5-9) points. Chronic lower-abdominal pain was the leading symptom in 86% patients, followed by recurrent leg (9%) and vulvar (5%) varicosities. The main PVD pathologies were ovarian vein insufficiency (61%), internal iliac vein insufficiency (9%), or a combination of both (30%), whereas 42% had a deep venous obstruction of the inferior vena cava, common iliac or left renal veins. Endovascular therapy included ovarian vein embolization (86%), internal iliac vein embolization (9%), and venous stent placement (35%). After a median of 4 (IQR 1-8) months from endovascular treatment, 40 (93%) patients reported improvement of the leading symptom, and 14 (33%) were symptom-free. Complications included re-intervention for stent stenosis (13%, all post-thrombotic), coil-migration into the left renal vein (7%, all retrieved), and transient pelvic sclerotherapy-induced thrombophlebitis (2%). Conclusions: Endovascular therapy following a diagnostic approach, which included a PCS screening tool and non-invasive imaging, appeared to be highly effective and was associated with a low rate of complications.

RESUMO

Lumbar lordosis is one of the most important parts of the spine, which is of special importance due to its unique position and direct contact with the pelvis. The aim of this study was to combine the results of several studies and to evaluate the magnitude of the effect of different Lumbar lordotic angle correction programs through meta-analysis. This study has been developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. Four databases were searched for articles collection: PubMed, Cochrane Library, Web of Science, and Google Scholar. The key search terms were: "Lumbar Lordotic angle", "Lordosis", "Hyperlordosis", "Corrective exercise", and "Low back pain. "The articles included in our study were limited to original articles written only in English that met the following inclusion criteria: (1) participants with lumbar lordosis or hyperlordosis or low back pain; (2) different programs of corrective exercises were applied; (3) Lumbar lordotic angle used as outcome measures. Ten studies are included in our systematic review and meta-analysis. The effect size for the Lumbar lordotic angle outcome was (SMD = 0.550, p ˂ 0.001, moderate effect size). Subgroup analysis for Lumbar lordotic angle: Subgroup Younger group (SMD = 0.640, p ˂ 0.001), Subgroup Older group, (SMD = 0.520, p ˂ 0.001). Subgroup Treatment (SMD = 0.527, p ˂ 0.001), Subgroup No treatment (SMD = 0.577, p = 0.002). This was the only outcome assessed in our analysis. The current meta-analysis indicates that different correction methods have a positive effect on subjects with lumbar lordosis or hyperlordosis. In the following research, we should try to determine which corrective methods have the best effects.

RESUMO

Current studies indicate that robotic-assisted surgery is not inferior to laparoscopic or open surgery regarding oncologic or functional outcomes. An exception may be uterine cervix cancer, where the survival after minimal invasive surgery might not be as good as after open surgery. There is less bleeding and need for blood transfusion after robotic-assisted surgery, and postoperative complications are similar to open or laparoscopic surgery. Robotic-assisted surgery offers ergonomic advantages compared to laparoscopic surgery. The effect of the surgical learning curve is not sufficiently studied. Presently robotic-assisted surgery is not cost-effective due to high costs of investments. The operation is more time consuming than laparoscopic or open surgery with risks of delaying and cancellation of other operations.

RESUMO

BACKGROUND: There is progress to be made in building artificially intelligent systems to detect abnormalities that are not only accurate but can handle the true breadth of findings that radiologists encounter in body (chest, abdomen, and pelvis) computed tomography (CT). Currently, the major bottleneck for developing multi-disease classifiers is a lack of manually annotated data. The purpose of this work was to develop high throughput multi-label annotators for body CT reports that can be applied across a variety of abnormalities, organs, and disease states thereby mitigating the need for human annotation. METHODS: We used a dictionary approach to develop rule-based algorithms (RBA) for extraction of disease labels from radiology text reports. We targeted three organ systems (lungs/pleura, liver/gallbladder, kidneys/ureters) with four diseases per system based on their prevalence in our dataset. To expand the algorithms beyond pre-defined keywords, attention-guided recurrent neural networks (RNN) were trained using the RBA-extracted labels to classify reports as being positive for one or more diseases or normal for each organ system. Alternative effects on disease classification performance were evaluated using random initialization or pre-trained embedding as well as different sizes of training datasets. The RBA was tested on a subset of 2158 manually labeled reports and performance was reported as accuracy and F-score. The RNN was tested against a test set of 48,758 reports labeled by RBA and performance was reported as area under the receiver operating characteristic curve (AUC), with 95% CIs calculated using the DeLong method. RESULTS: Manual validation of the RBA confirmed 91-99% accuracy across the 15 different labels. Our models extracted disease labels from 261,229 radiology reports of 112,501 unique subjects. Pre-trained models outperformed random initialization across all diseases. As the training dataset size was reduced, performance was robust except for a few diseases with a relatively small number of cases. Pre-trained classification AUCs reached > 0.95 for all four disease outcomes and normality across all three organ systems. CONCLUSIONS: Our label-extracting pipeline was able to encompass a variety of cases and diseases in body CT reports by generalizing beyond strict rules with exceptional accuracy. The method described can be easily adapted to enable automated labeling of hospital-scale medical data sets for training image-based disease classifiers.

RESUMO

The bladder is a rare site for breast cancer metastases, and only occasional reports are present in the literature. Most cases coexist with synchronous metastases elsewhere, but isolated cases of a single metastatic localization in the urinary bladder have been reported. The most common symptoms of a metastatic localization of breast cancer to the urinary bladder are hematuria and voiding dysfunction. Herein we present three cases of urinary bladder metastasis from breast carcinoma, all presenting with gross hematuria as the only symptom. After a review of the relevant literature, we discuss the clinical and histological characteristics unique to our cases, highlighting potential clinical and pathological diagnostic pitfalls and differential diagnoses.
