Fibroepithelial polyps (FP) of the ureter are rare and benign mesodermal tumors frequently mistaken for transitional cell carcinoma. We hereby report a rare case of a 19-year-old patient with two FPs, originating from the distal left ureter that were successfully treated with ureteroscopy. One of these polyps was completely protruding outside the bladder through the urethra, which makes this case unique in the literature. Ureteroscopy is currently the best method available for identification, histologic diagnosis and treatment of these polyps.

Quality control is an essential operation for an automotive company like Faurecia. A vast number of references is produced, and many regions of interest need to be checked. For that, quality control is necessary and should be applied to every reference part. Visual inspection is achieved by the operator who checks each part manually. After several checks per day, the operator gets tired and thus may misqualify a welding seam or a component control. To avoid that, Faurecia is trying to integrate automatic quality control to obtain better overall equipment effectiveness (OEE), especially to avoid performance degradation over the operator's shift. Researches demonstrate the ability of a neural network to reach high precision in detecting object presence or absence. We have been able to achieve an accuracy of 99% with ResNet-50. Apart from accuracy, the other performance matrices used in this work are reliability and cycle time. Our contribution will help the current state of manufacturing by offering an automatic visual inspection, which will lead to other innovative projects in the automotive industry.

Introduction and Objectives. Lichen sclerosus (LSc) is a chronic inflammatory process of the skin characterized by its unique histological features. It affects men and women of all ages, mainly in the anogenital area. The etiologies and exact pathophysiology are not well-known; however, LSc can be considered a precursor to male genital squamous cell carcinoma. We aim, through this case-control study, to potentially associate genital LSc with risk factors and certain patient characteristics in Lebanese adult males. Materials and Methods. A nested case-control study design was chosen. Subjects enrolled were adult male patients who had a circumcision between January 2010 and December 2020 at our university hospital, with a confirmed LSc diagnosis on pathology. Cases were matched with controls by age with a ratio of 1 : 1, all of whom were circumcised and had a negative pathology report. Data collection consisted of sociodemographic, behavioral, and past medical and familial history characteristics. Results. A total of 94 patients were enrolled. The mean age was 49.81 (±22.92) in the group of men with LSc. No significant differences in sociodemographic characteristics (age and BMI) were found between the two compared groups. Smoking cannot predict LSc as opposed to alcohol consumption, which we found to be a protective factor against the appearance of LSc ( p = 0.027 ). Men with LSc had significantly higher rates of diabetes ( p = 0.021 ) and hypertension ( p = 0.004 ). No associations were found between LSc and the presenting chief complaints, family history of LSc, and past penile trauma. Conclusion. In this study, we were able to compare multiple variables between 47 circumcised patients diagnosed with LSc and a control group. We found that LSc patients showed higher rates of diabetes and hypertension. A potential protective effect of alcohol consumption is to be explored in future projects with bigger sample sizes and higher statistical powers.
